Shin Splints: Symptoms, Causes, Treatment & Prevention

In this article, you’ll not only learn how to self-treat your shin splints, but also what causes this type of shin pain, and how to fix the underlying causes of this common running injury.

I’ll help you discover how to prevent shin splints so that you can return to running successfully without shin pain.

We’ll cover:

Let’s being with understanding the problem itself…

What are Shin Splints?

Shin splints, or Medial Tibial Stress Syndrome (MTSS) to use the medical term, is a very common injury amongst runners. In fact, some studies have reported shin splints to occur in nearly twenty percent of the running population.

Shin splints are an overuse injury to the tibial (shin) region of the leg, caused by repetitive impact and strain on the shin and surrounding tissues. Shin splints occur when frequent stress on the shin exceeds the body’s capacity to recover from micro-damage caused by the stress.

In the initial stages of shin splints, the pain is caused by a stress reaction to the tibia, and damage to the periosteum around the bone. In more severe cases can turn into tibial stress fractures.

Out of all of the running injuries that I regularly treat, I think this one is the least well understood, in terms of exactly what’s going on.

It’s an injury that I have a personal history with. When I took up running again, after a long absence, it was the first injury I got. The resulting frustration is what kick started my journey into wanting to better understand running injuries in general, not just my shin splints pain.

Like so many of the running injuries we see in the clinic every day, shin splints is classed as an ‘overuse injury‘. It does appear in other sports, but is certainly much more prevalent in runners.

In addition, it definitely seems to be a condition that affects novice runners more than fitter, more experienced athletes, the reason for this should become clear later on in this article…

Soft tissue treatment for shin splints

What does shin splints feel like?

In typical cases, shin splints pain is usually felt two-thirds of the way down the tibia, just off the inside edge of the bone.

In the early stages, shin splints pain is usually felt at the beginning of a run and then normally subsides during the training session itself. Commonly, symptoms also tend to reduce a few minutes after a given run session has finished.

If the injury worsens, shin splints pain is felt in less intense activities and can be present at rest.

It is often painful to apply direct pressure to the affected area. Because the anteromedial border (front/inside) of the tibia is directly under the skin, pitting oedema, and even callus formation, can be felt on upon close examination in some cases.

This is thought to be a response of the periosteum to micro-fracture formation.

What Causes Shin Splints?

So, what exactly is going on to cause shin splints!?

As I mentioned earlier, when it comes to knowing what causes shin splints, there are various potential mechanisms causing this kind of lower leg pain. These, and even which structures are involved, are still up for debate.

Let’s look at a few of the more plausible theories as to what causes shin splints:

1. Tight Calf Muscles

One group of suspects, in this case, are the soft tissues of the tibial region. The muscles of the calf, and the smaller muscles of the ankle, have their attachments along the tibia. Specifically, the tibialis posterior, flexor digitorum longus and soleus muscles, have been implicated as possible sources of injury.

The theory being, that tightness, weakness, or excessive movement at the ankle causes traction or tugging at the site of their origin on the tibia, leading to an irritation of the periosteum.

However, this theory doesn’t really stand up to anatomic scrutiny, in that, all of the above-mentioned muscles, have their origins above the site of shin splints pain. It seems unlikely that traction of an origin site, higher up the tibia, would produce pain at the distal (lower), medial (inner) shin.

There is, however, another soft tissue that does attach to the medial border of the tibia, in the location of the symptoms. That structure is the deep crural fascia (fascia is a thin sheath of fibrous tissue enclosing muscles and organs).

This structure has deep insertions to the medial tibial border, finishing at the medial malleolus (inside ankle bone). It’s highly likely that the above-mentioned muscles will be continuous with this fascia.

Therefore, from an anatomical point of view, the deep crural fascia could tug on the periosteum, in the location of symptoms, and create the traction mechanism of injury detailed above.

2. Weak Calf Muscles

Some studies have suggested that smaller calf size, and decreased calf strength, could be connected with shin splints.

The theory being, that it is the bone tissue of the tibia itself, that is the source involved in the pain response.

Bigger, stronger calf muscles encourage the tibia to become stronger, and therefore, able to take greater loading.

Additionally, the calf muscles themselves being stronger, would mean they would be able to absorb impact forces directly, again taking the load off the tibia.

3. Overload of the Tibia (Shin Bone)

This alternative explanation for why shin splints occurs, again implicates the tibia itself. This hypothesis suggests that the problem arises via micro-trauma to the bone, due to repeated bending or bowing of the tibia.

Tibial Bending / Bowing

It is well known in engineering, that when you load a long, narrow structure (like the tibia) axially, e.g. place a force through the centre of the object, lengthwise, it will result in bending moments at the structure’s lowest cross-sectional area (the narrowest part). The narrowest part of the tibia is the distal third where symptoms of shin splints are commonly felt.

It is generally suggested by biomechanists, that the tibia bends in the sagittal plane (forwards and backwards plane of movement) when running, placing most force at the distal anterior section of the tibia. But this, of course, depends on form; dictating where and how you strike the ground as you run.

Pole Vaulter Analogy

Think of this a bit like a pole vaulter’s pole…

As they approach the jump, they plant the pole ahead of themselves (similar to an over-stride when running). Subsequently, when you see this big, anterior bowing of the pole. Great for pole vaulting but not so good for shins!

If we factor in three potentially important elements, we see that this anterior bowing force, in many runners, will be shifted medially, to where the symptoms of shin splints are reported.

  1. As the foot loads, pronation occurs, (we all do it to varying degrees) which will shift the ground reaction force more towards the medial shin, and cause more of a varus (side-bending) force in the tibia.
  2. Pronation is usually coupled with medial rotation of the tibia, which also places more stress medially.
  3. When we run, we tend to land more towards the midline than directly in line with our hip. This is because it’s easier to get our centre of mass over our base of support. The consequences of this, are that our tibias will absorb the ground reaction force at an angle, and therefore a varus (side-bending) force, will again, be applied to the medial tibia, at the part of the tibia with the least cross-sectional area e.g. where most people with shin splints have their symptoms.

Other Factors Which Add to Tibial Stress

Additionally, the muscular contractions of our plantar flexors, namely soleus, can also cause a tibial bending moment. If you imagine the attachment site of soleus, at the top of the tibia, and its insertion at the calcaeneus.

As we go through mid-stance, and the soleus begins to contract to slow the acceleration of the tibia, the origin and insertion sites will be pulled towards each other, again causing an anterior bending in the sagittal plane.

It is important to note at this point, that bone stress is not a problem, if it’s applied at a gradual rate. Bone is an organic and dynamic structure. Like all living structures in the human body, it responds to stress by remodelling itself, to ensure it can cope with the demands being placed on it.

The problem comes, when the accumulated stress of training, outstrips the body’s ability to remodel the area. This gives us an insight into why this condition is more prevalent in novice runners, or less fit runners, because their bones have not adapted over time to the stress of repetitive, high impact exercise.

It also gives us another layer of evidence to illustrate that, when it comes to shin splints prevention, it may not be the sexiest intervention, but the most fruitful therapy is to obey the law of adaptation, and accumulate the stress slowly, giving your body’s tissues the chance to adapt and get stronger and therefore be able to withstand greater load.

The tibial bending theory has not been proven yet, but it certainly seems to me, to be the most persuasive of the current theories on offer. As always I’ll allow this to guide my practice, whilst keeping an open mind and following any further developments in the literature.

Other Potential Causes of Shin Pain

There are of course a number of differential diagnoses which can also cause shin pain, which would be easy for the untrained eye to mistake for shin splins. These include:

  • Stress fracture – Interestingly, some authors feel that stress fractures are on a continuum with shin splints, whereas others feel they are similar but different conditions.
  • Chronic exertional compartment syndrome or anterior biomechanical overload syndrome.
  • Popliteal artery entrapment
  • Tibial tumours
  • Bone infections / Osteomyelitis

How to Prevent Shin Splints

Prevention is always the best medicine when it comes to running injuries. Shin splints are similar to most running injuries, in that the most effective means of shin splints prevention is to respect the laws of adaptation. This means, firstly, listening to your body.

If you are feeling pain when running, it’s because your brain has decided, that a particular area of your body needs protecting. Usually, but not always, this is because too much stress, or load, is being accumulated in the painful area, and you are not leaving enough time in between stresses to allow the tissues to adapt.

So the key to shin splints prevention is gradual, patient loading.

How to Treat Shin Splints

Now, if you’ve gone past the shin splints prevention phase and are in the painful phase (and let’s face it, if you’ve found this article, I imagine you’re in this phase already) the next sections will be helpful for you.

Pain Relief for Shin Splints

The reason that most people visit me is due to pain. Pain is often viewed as the problem. It isn’t. Pain is a symptom of the problem. Your pain system is complex and has evolved through millions of years of natural selection. It is essentially your alarm system.

Its purpose is to protect you, and alert you, to the fact something is not right. It’s not a nice feeling, but at the end of the day, it’s meant to be uncomfortable, otherwise you would ignore it!

Pain is your friend.

Dealing with pain is important, no-one wants to be in pain, it’s not a nice sensation at all and, to be fair, once we’ve worked out what the problem is and how to address it, the sensation becomes less helpful, so turning it down a bit is one of the early goals of physiotherapy.

Remember that we want to turn the pain down, but we have to work out why it’s is there in the first place, otherwise it’s like your burglar alarm going off, you getting annoyed and fed up of the repetitive, annoying sound and going to the box and turning it down.

It may make the noise a bit more bearable but does nothing to address the intruder in your house (a bit of a dramatic analogy, but you get the point).

When it comes to pain relief I try to keep it simple:

Ice & Cold Therapy for Shin Splints

Ice works really nicely as an analgesic for shin splints pain. Crushed ice appears to be more effective from the current research. Rough guidelines of 10 mins every 2 hours, if needed, are adequate (Remember to wrap ice in a damp towel to prevent ice burns).

Decrease the load on the sensitive area. Intuitively, if you continue to stress, the already over-stressed area, it will prevent healing or de-sensitisation. Decreasing the load can be as simple as rest, cross training or, my favourite option, running re-education – see below.

Medication for Shin Splints Pain

Some pain medications can be helpful in managing the pain of shin splints. Always consult your GP or pharmacist before taking any medication.

Running Technique for Shin Splints

The goal of running technique coaching is to assess an individual’s running style, and see if, through subtle changes to their biomechanics, you can shift the load from the area of shin splints pain, whilst not jeopardising their performance or creating an environment for another injury elsewhere in the body.

So in the case of shin splints, we are trying to reduce the anterior and medial tibial bowing.

Here are some of the running cues that I like to try with this condition. It’s important to note that there is huge variability in what works for different patients.

Word of warning with these: If the cue is going to work for you, you should feel marked relief, and ideally no shin splints pain at all, within 30-60 seconds of adopting the cue.

If you’re not getting any relief of your pain by then, don’t run through shin splints.

If none of the below cues are working for you, then it may be time to see a physiotherapist, or other health care practitioner, for some advice, ideally make it someone who specialises in running injuries.

Increase Running Cadence for Shin Splints

One of my most used running re-education cues across the board. The best way to do this is with the aid of a digital metronome.

There are lots of free metronome apps, if you have an iPhone, or you can buy a digital metronome pretty cheaply from places like Amazon.

There’s no set stride rate you should aim for so have a play around with it. Generally, I go for 5%-10% more than your current cadence and see what happens. You can always gradually increase it from there and re-assess the ‘experiment’.

The theory behind increasing your cadence is to decrease an overstride, get you landing closer to your centre of mass (COM) and with a straight tibia, as opposed to your tibia flicking out ahead of the knee.

As mentioned earlier this article, think of it a bit like a pole vaulters pole. As they approach the jump, they plant the pole ahead of themselves so you see this big, anterior bowing of the pole, great for pole vaulting but not so good for tibas!

If you can imagine the pole vaulter placing the pole down vertically, and not ahead of themselves, you will see a pretty crappy pole vaulter, but also less anterior bowing of the pole, that’s what we are looking for – less anterior bowing = less force through the painful area.

Increase Step Width for Shin Splints

Trying to move the load from the medial shin, to achieve less varus (side bending) tibial bowing. I try to bring about this change using a variety of cues. Generally, asking people to have some daylight between their legs or imagine running on either side of a yellow parking line, gets the right changes.

Recently, I’ve been getting my runners to run with a resistance loop just above their knees, and instruct them to keep the pressure on the band – this has been working really well.

Here’s a quick video about running step width:

Increase Ankle Stiffness

The idea here is to decrease the amount of dorsiflexion the ankle goes through. Lessening dorsiflexion means less tibial bowing from the action of soleus, as it tries to decelerate the tibia as it moves into end of range dorsiflexion.

Stiffening the ankle also helps to pretension the muscles, so they can work reactively and elastically. Good for speed but also takes the load of the bone itself.

A great way to train your body to naturally increase ankle stiffness is to start using a skipping rope. Jumping rope is a low-level plyometric drill, great for training ankle stiffness.

One word of warning though… Seeing as you’re recovering from shin splints, use this sparingly. Aim for 5 rounds of 20 seconds three times weekly to start with.

More information on plyometrics for runners can be found here.

Change the direction of the ground reaction force

Again, we are trying to decrease the anterior tibia bowing. If we go back to our rubbish pole vaulter, as we discussed if he places the pole out in front of him with forward and downwards force it will create anterior bowing.

However, if he plants the pole down with a backward and downwards force, it will not bow anteriorly, but posteriorly. Bad for a pole vaulter, but good in our tibial context! i.e the force will go more through the back of the tibia.

Any change in the direction of the ground reaction force, to a more backwards and downwards force, will decrease the load in the anterior tibia and may be enough for us to keep running without pain. To cue this, I often video them and freeze the frame of them running when their swing leg is at its highest.

From this position, I instruct them to push their leg back and down in a backwards tick type direction, using their glutes to perform the movement. Sometimes I’ll ask them to paw back on the ground (bit of a controversial cue from a performance perspective, but can just get them to direct the force more backward and down).

Running Posture for Shin Splints

When it comes to running posture, I usually encourage the patient to ‘run up tall’. I often use the ‘helium balloon attached to the crown of the head’ cue or get them to imagine their spines like a slinky toy, and wanting to open it up. This cue helps decrease an anterior pelvic tilt, or a forward lean from the waist.

Both of these mechanics lead to the centre of mass shifting forwards during stance. To compensate for this, you will have to over stride with the next step = more load on knee and shin area.

Usually, I use a combination of the above. Have a play around with these cues and let me know what works for you. As always, never run through shin splint pain.

There are some occasions when no matter what alterations you make, you can’t offload the area sufficiently and pain is still present. In those cases, it is wise to take a short break from running, to allow the area to settle some more.

Cross-training can be effective at this point, to maintain strength and fitness. Remember you only need to offload the painful area, not your whole body. I prefer aqua-jogging, or running on an alter-G treadmill (if you’re lucky enough to have access to one).

This way you can still work on technique, and keep your running specific movement patterns with very little stress on the musculoskeletal system.

Here’s a quick video with some more running technique tips:

Other Shin Splints Treatment Techniques

Here are a number of additional treatment techniques you may want to consider if you are currently suffering with shin pain.

Orthotics for Shin Splints Pain

Generally, I try to avoid orthotics or taping if I can, but they can still be great tools to offload an injured or sensitised area. Often medial arch supports works well to offload the medial tibia.

Calf Strengthening for Shin Splints

As mentioned earlier, weak calves have been implemented in shin splints. So seems like a good idea to strengthen these muscles as a way to create a stronger lower leg region in general, but also being able to take more load themselves.

Changing the Surface you run on?

Bit of a weird one this, intuitively you would think that running on softer ground, such as an athletics track, sand or grass, would be easier on the legs, but the literature suggests that when we run on softer ground our leg actually stiffens more to compensate for the softness, and the reverse is true when running on hard ground i.e. less stiff legs.

This has led many to suggest that it may be better for runners with shin splints to run on harder ground. I remember when I had my shin splints, I found it better running on softer ground, but might be worth bearing in mind if you find the shin splints pain is worse on softer ground.

Barefoot Running and Shin Splints

There is some evidence that barefoot running (or barefoot style) can shift the load from the shin and knee, more to the foot and ankle. Probably by, subconsciously, increasing cadence and landing closer to CoM.


So these are my current thoughts on this interesting (to me anyway) topic. I hope it’s been a helpful read for some of you out there who are currently struggling with shin splints.

Let me know how you get on. I will try to update this post if any new evidence for how to treat shin splints comes out, or if I find success with any new techniques, cues and exercises for shin splints in my clinic.

Remember; one of the best ways for how to prevent shin splints in the first place is to avoid the temptation to do too much too soon. When you are on returning to running, please do bear this simple tip in mind!

Good luck with your rehab.

How Long Does it Take to Recover From Shin Splints?
Last updated on August 10th, 2023.


  1. Nice article. I have found tight gastroc/soleus is often implicated in anterior shin pain as the extensors help out with the lack of available dorsiflexion. Any thoughts?

  2. would like to know how to strenthen walking on the heels and outer part of foot….when foot drop and week doesiflexion???

  3. Good and clear article. Well done.
    After the diagnose ‘shin splint’ my sports doctor prescribed three things. Rest, and after that very slow (very frustrating) rehab program. And excercises for strenghten my ankles. Some of them also strenghten the calf.
    Now I’m free of pain for more than a year. So the article describes perfectly my situation and solution to the problem.

  4. Excellent article. I used to get shin splints a lot but haven’t done so for about 10 months now. I am an older runner and came into the sport only 3 years ago. As the article says, prevention is key for me. If you have been plagued by shin splints in the past, you might find the following helpful: 1. Find out what you can get away with and what you can’t. I have found I need a day of not running after each day running (when I X train instead). 2. Don’t increase mileage by more than the 10% rule (it is very reliable). 3. I use orthotics with special cushioning for running. 4. Sort out technique as above and concentrate on reducing stride length, to try and increase cadence and get towards mid-foot (or at least glancing heel-strike) landing (this also helps with runners knee). 5.I try not to run on concrete or cambered surfaces. Flat trail is best. Road or flat, mown grass second best for me. (I don’t use a treadmill now). Running on uneven grass surfaces in the dark can cause other injuries. I always stick to road (well lit if possible) in dark, winter months. 6. I never do more than one quality session a week (eg interval training, threshold-paced runs), and I avoid steep hills completely now, which are bad for runners knee. Most of the roads near where I live have a gentle incline anyway, which is no problem for knees and helps to build fitness.7. Warm up properly beforehand (there are some excellent warm-up exercises for shin splints prevention on the KR website, which I always do now before running). 8. Stretch all muscle groups properly after running (as per KR website instructions). 9. Do at least one session a week concentrating on core and conditioning of all major leg muscle groups, and especially the glutes I now run every other day (3-4 runs a week), including one threshold session, one long run and 1-2 easy-paced runs, and have not had an injury since May.

  5. Question. How do you stiffen the ankle? Is it a case of stiffening the ankle joint or decreasing the ankle joint range?

  6. Thanks for sharing – it’s true, pain is your friend! PS any studies on taller (longer tibias) being more prone to shin splints? Just thinking of the forces involved.

  7. Thank you! Finally a fully informative and useful article!
    I have shin splint and have rested up for months. I’m getting back in to running but still experiencing issues. I’ll be sure to try some of the suggestions to see what works for me. I’ve down the icing but good to know about not directing on the area – which I have been doing.
    I have also run on on softer ground along a canal but think the unevenness of that is no good – it has to be even soft ground for me. I use a foam roller too and also have a resistance band to try and strengthen my ankle. My shin splint won’t be sorted any time soon but patience (which I’m rubbish at!) and commitment to doing all the stretches etc are key. I’ll definitely be trying the different styles of running suggested here too – anything or get me back to running!

  8. I think if you are getting shin splits its,quite likely that you also have weak arches. If your foot has “grown” in adult life, your arches are probably slowly collapsing. The posterior tibialis (inside calf) has to work hard to compensate & you may find knotts here also. Weak glutes seem to be on trend to diagnose most running issues & while I do think a strong posterior chain, I think the foot arch is neglected. Its so easy to fix. Yoga balance poses are excellent, keeping the weight on the ball of the foot. Walking in minimal shoes also helps.

  9. Nice article. I am a long term sufferer of shin splints and I really really wish more people would take notice of shins splints and think more about them before they start running. The latest figures apparently show that as much as 20% of runners suffer from shins splints, my guess would be that that figure could easily be as high as 50% as most runners don’t report their injuries to doctors and try to run through the pain, please don’t do this, I did this and caused a fracturing of my shin which almost took me out of running forever.

    Please educate yourselves, read up on sites like this and and get the tools, equipment and education you need to keep yourself running for years to come.

  10. I’ve had shin splints once, they started immediately as I ran on a gravel track. I managed to run one kilometre before the pain became unbearable, I turned and hobbled back in agony. I stretched through the pain once back and the pain subsided. That was over 12 months ago, I’ve never had shin splints since and now run 30k per week. Great article, and perhaps answers the mysterious case of shin splints.

  11. This is a nice article actually. Finding a place to help my shin splints and I might actually apply this to my runs from next week. Stiffening my ankle might be a good fit.

    Now, I have tried to find a pair of decent, but inexpensive running shoes for my shin splint pain during my cycling and walking sessions. I cycle a lot and need something that are comfy and easy to fit (As I have wide feet)

    What do you think of this post? I like the Hoka’s but I want to see what you guys think:

    Thanks in advanced!
