Shin splints
Also called: medial tibial stress syndrome, shin pain from running, MTSS, tibial stress. Clinical name: Medial tibial stress syndrome (MTSS).
With training modified, most shin splints settle over 2–6 weeks, with a gradual return to running from around week 4. One-spot pain on the bone, or pain at rest, needs a check for a stress fracture.
What it actually is
Shin splints, medial tibial stress syndrome to clinicians, is pain along the inside edge of the shin bone caused by overload of the bone and the tissues that anchor muscle to it. It is overwhelmingly a running injury, and more precisely a change-of-load injury: the story almost always includes more miles, more speed, harder surfaces, a return from a break, or a new sport with more impact than the legs were prepared for.
The pain usually starts as an ache during the first minutes of a run that warms up and fades, then returns afterwards. Left alone, it stops warming up: it hurts throughout runs, then on walks, then on stairs. That progression matters, because at the far end of the same spectrum sits the tibial stress fracture, a small crack in the bone with a much longer timeline. Diffuse tenderness along the bone points to shin splints; one exquisitely tender spot points to something that needs imaging.
The recovery is rarely complicated but demands honesty: drop the impact load until pain settles, strengthen the calves and feet, fix the shoes, then rebuild mileage gradually with pain as the veto. Runners hate the first half of that sentence and skip the second, which is why shin splints have a reputation for dragging on. Tracked and managed, they are usually a six-week detour rather than a season-ender.
How bad is it?
Shin splints are not graded like a tear. What matters is the pattern: early-stage shin splints ache at the start of a run, ease as you warm up, and grumble afterwards; established shin splints hurt throughout runs and start intruding on walking and daily life. The critical distinction is with a tibial stress fracture: shin-splint pain is spread along several centimetres of the inside of the shin bone and eases with rest, while stress-fracture pain concentrates into one small, exquisitely tender spot and can start hurting at rest or at night. Focused one-spot pain is the sign that should send you to a clinician rather than back onto the road.
How long will it take?
Recovery moves in phases. This is the typical shape of it — yours may run faster or slower, and the numbers below are general ranges, not a forecast for your specific injury.
When to get it looked at
Most cases settle with time and sensible loading. Get it assessed by a professional if any of these apply — they can point to something that needs hands-on care:
- Pain concentrated in one small spot on the shin bone that is exquisitely tender to press (possible stress fracture)
- Shin pain at rest or at night, or pain that makes you limp during normal walking
- Pain with swelling, tightness and numbness in the lower leg during exercise that eases quickly on stopping (possible exertional compartment syndrome)
- A hot, red, swollen shin or fever
- Pain that is getting worse despite two or more weeks of sensible rest from impact
This is a list of warning signs, not a diagnosis. If you are worried, or the pain is severe, see a GP, physiotherapist or urgent care.
What to track while you recover
Shin splints live and die by training load, and the pattern only becomes visible when it is written down. A short daily note of pain against mileage is exactly the evidence that separates a manageable grumble from a brewing stress fracture.
- Pain score, 0–10, during the run, after it, and the next morning (the next-morning score is the most honest one)
- Distance, surface and shoes for every run or impact session
- Whether the pain is spread along the shin or focused in one spot you can cover with a fingertip
- Cross-training and calf-strengthening sessions done
- Rest days, and whether the shins felt better or the same after them

What to tell your physio
A clinician assessing shin pain is mostly trying to separate shin splints from a stress fracture and find the training error. Your log answers half their questions before they ask.
- Your training in the weeks before it started: any jump in mileage, speed work, new surfaces or new shoes
- Exactly where it hurts, spread along the bone or one spot, and whether that has changed
- When it hurts: start of a run, throughout, afterwards, walking, or at rest
- What you have already tried: rest, ice, new shoes, insoles, and what difference each made
- Your running history and goal race or season, so the return plan fits the calendar

The questions people actually ask
How long do shin splints last?
With the training load actually reduced, most cases settle over two to six weeks, with a gradual return to running from around week four. Push through unchanged training and they routinely drag on for months, or graduate into a stress fracture. The timeline is driven less by the calendar and more by behaviour: the runners who cut volume early and rebuild gradually get back fastest, which is one of the small ironies of this injury.
Do shin splints go away on their own?
They go away when the load on the shin drops below what the tissues can handle, and not before. For someone who overdid a single week, a fortnight of easy training may be enough. For a runner who keeps stacking miles on sore shins, they will not vanish on their own, because the cause is still being applied daily. Rest from impact settles the pain; fixing the loading error, the footwear and the calf strength is what stops it coming straight back.
How do I know if it is shin splints or a stress fracture?
Shin splints typically hurt along a stretch of the inside of the shin bone, several centimetres of diffuse tenderness, worse with impact and better with rest. A stress fracture concentrates: one small spot that is exquisitely tender to press, pain that appears earlier and earlier in runs, and eventually pain with walking, at rest or at night. Hopping on the leg tends to be very provocative with a fracture. If your pain has narrowed to a fingertip-sized spot, stop running and get assessed; the two injuries have very different timelines.
Can I keep running with shin splints?
Sometimes, at a much reduced dose. Mild, early-stage shin splints often tolerate short, easy runs on soft surfaces with rest days between, provided pain stays low during the run and does not linger the next morning. What does not work is running the same mileage and hoping. If pain climbs during runs, lasts into the next day, or makes you change your stride, switch to cycling or pool work for a couple of weeks; you lose almost no fitness and you buy the shins the break they are asking for.
What causes shin splints?
Overload, in one form or another. The classic triggers are ramping mileage or intensity too fast, lots of running on hard surfaces, worn-out or unsuitable shoes, and calves and feet that are not yet strong enough for the load being asked of them. Beginners and returning runners are most at risk precisely because bone and tendon adapt more slowly than cardiovascular fitness, so the engine outruns the chassis. That is also the logic of the fix: build the structures with calf and foot strength while reintroducing load gradually.
What are the best exercises for shin splints?
The evidence points less at a magic exercise and more at capacity building. Calf raises (both straight-knee and bent-knee versions, building towards single-leg), toe raises for the muscles at the front of the shin, and foot-strengthening work form the core. Hip and glute strength help control how hard each stride lands. None of these are a substitute for sensible training load, but done consistently for a few weeks they raise the amount of running your shins can absorb without complaint.
