CHECK 01
One fingertip, or the width of your hand?
Do this before anything else. It takes ten seconds and it is the single most useful thing you can tell someone about your shin.
Sit down. Run a finger slowly up the inner edge of your shin bone, from just above the ankle towards the knee, pressing as you go. You are answering one question. How much of it is sore?
A diffuse ache spread along more than about five centimetres of that inner border, roughly a hand's width, is the picture that fits the thing people actually mean by shin splints. One sore spot you could cover with a single fingertip is a different conversation entirely, and it belongs on the get-it-looked-at list rather than the train-through list.

Write down how many fingers wide the sore patch is, and where it sits. That one line changes the conversation more than any scan you could book.
CHECK 02
Watch what it does after you stop.
The settle tells you as much as the pain does. Three problems, three completely different exits.
A shin splints ache grumbles on. Hours, sometimes into the next day. It is a slow fade, and it is usually worst first thing after the session rather than during it.
Compartment pressure vanishes. Minutes, not hours. If your shin is furious at mile four and completely fine by the time you have walked back to the car, that is a different mechanism and it needs a different answer.
Bone stress does not really settle at all. It is there when you sit still. It is there at night. That is the one that changes the plan today rather than next month.
Time it. Note how long it takes to go quiet after you stop running, and whether it is still there in bed. Minutes, hours, or never is the most useful sentence you can bring to an assessment.
CHECK 03
Something changed. It probably was not your feet.
Look at the four to six weeks before it started. A block of mileage. A comeback after a lay off. New surface, faster sessions, a race build, a job that put you back on your feet all day. Something almost always changed.
Your arches are collapsing, and that is why your shins hurt.This is the story most runners get handed, and the ground underneath it is thinner than you would think. Pool every study that has measured it and the difference in arch drop between runners who got shin splints and runners who did not was 1.19 millimetres. Barely more than a millimetre. It is a real difference across a group and it is close to useless as an explanation for your shin. The same review found ankle dorsiflexion and knee angle were not risk factors at all.
The honest list of what is associated with it: a higher body mass, slightly more ankle and hip range, being female, and by some distance the strongest one, having had it before. Notice what is missing. None of those are things you fix by changing your foot.
What you can actually change is the load. Watch for the spike rather than trusting a formula, because the formulas do not hold up. The 10% rule failed the only trial that ever tested it. The popular training load ratio predicts injury no better than a made up number in its place. What does survive scrutiny: risk starts to climb once weekly increases get past about 30%.
One thing worth trying while you rebuild. Nudging your cadence up by around 5 to 10% lowers the load going through the shin, and at that size it barely costs you anything in effort.
You can name what changed. If you cannot, the answer is usually hiding in the four weeks before it started, not in your arches.
WHY IT KEEPS COMING BACK
It is bone. Not muscle pulling on bone.
Here is the part most runners never get told. The old explanation, that your calf muscles tug on the lining of the shin bone and inflame it, is not supported by the tissue studies. When researchers actually looked at the tissue, they did not find the traction injury the story predicts. What they found was bone. The tibia remodelling under load, with the breaking down running ahead of the building back up.
That single fact reorganises everything. It is why stretching the calf harder keeps disappointing people, and it is why this behaves like a bone problem, which is a slower and more patient animal than a tight muscle.
It also explains the trial results. In the largest study of shin splints treatment in athletes, 74 of them, everybody followed a graded running programme. One group added calf stretching and strengthening on top. One group added a compression stocking. Neither group did any better than the running programme on its own.
105 daysthe average time it took those athletes to get back to running, on a graded programme. Around three to four months, and the spread was wide. This is not a two week problem, and anybody promising you it is has something to sell.
One caveat, and the researchers put it in print themselves: nobody has ever compared a graded running programme against simply resting. So gradual loading is what the trials use and what the evidence describes, but the claim that it beats rest has not actually been tested. Anyone who tells you otherwise is going further than the evidence does.
What we do know is that having had this once is comfortably the strongest predictor of getting it again. The load that flared it is the load you go back to. If nothing has changed about how you build, the same shin is waiting on the same week.
Worth getting checked rather than training through: most shin pain settles with the load managed properly and a bit of patience. A few patterns deserve a prompt look instead:
- A pinpoint sore spot on the bone you can cover with one fingertip, especially if it is worse every single session
- Shin pain that wakes you at night, or aches while you are sitting still
- Pain on the front ridge of the shin that keeps building. That edge of the bone has a poor blood supply, and stress injuries there are known for healing slowly and badly. It is the one you do not run on
- Numbness, tingling, or a foot that starts slapping or catching as you run
- Tightness or swelling that builds at the same point in every run and disappears within minutes of stopping
- Shin pain that is not settling at all, even though you have genuinely backed the load off
And one that is easy to miss: in runners who are training hard while under eating, or whose periods have stopped, bone cannot keep up with the repair it is being asked to do. Recurrent shin and bone niggles in that setting are a signal to get fuelling and bone health looked at properly, not to push through. None of these are panic buttons. They are reasons to have it assessed before you build back.
Not sure which of these you are dealing with? Working that out is exactly what the initial Movement Therapy appointment is for.
90 minutes. A full assessment of how you move, what you load, and what has been building across your training. Hands on treatment where useful. An individualised plan and clear aftercare, built around your running and your goals, so you leave knowing exactly what to do next and why.
