Shin splints are among the most common complaints in running, particularly for people ramping up mileage or returning after time off. Here's an honest overview of what they are and how they're generally approached. Shin splints — medial tibial stress syndrome — is pain along the inner shin bone caused by the tissue there being loaded faster than it can adapt, and it's fundamentally a training-load problem rather than something you fix with a stretch.
Important: this is general educational information, not medical advice. Shin pain has several possible causes, some of which are more serious. If your pain is persistent, severe, or worsening, see a doctor or physiotherapist for proper assessment.
What shin splints actually are (the honest picture)
"Shin splints" is a colloquial term, most commonly referring to medial tibial stress syndrome (MTSS) — pain along the inner (medial) edge of the shin bone, typically diffuse rather than pinpoint. It's generally understood as an overuse injury involving stress on the bone and the surrounding tissue where muscle attaches. Classic presentation: pain that's worse at the start of a run, sometimes eases during, and returns afterwards, with tenderness along a stretch of the inner shin. Early on it may only hurt while running; as it progresses it can hurt during daily activity. It exists on a continuum — which matters for the warning signs below.
Why they happen (it's almost always load)
The dominant cause is straightforward: doing too much, too soon. The tissue simply hasn't had time to adapt to the load being placed on it. Specific contributors that show up repeatedly: rapid increases in running volume or intensity (the classic — new runners, or returning ones, adding mileage quickly), returning after a break at your previous level rather than building back, hard surfaces and sudden surface changes, worn-out or unsuitable footwear, overstriding and low cadence increasing impact loading, and weak calves, hips, and feet meaning less capacity to absorb force. Notice most of these are modifiable, which is the encouraging part.
The general management approach
Most approaches share common principles, and patience is genuinely part of it — this typically takes weeks, not days. Reduce the aggravating load — usually cutting running volume and intensity substantially, though complete rest isn't always required or ideal. Maintain fitness with low-impact alternatives — cycling, swimming, or the rowing machine let you keep training while the shin settles. Address the contributing factors rather than just waiting it out: calf strengthening, hip work, and checking your cadence and footwear. Return gradually — this is where people commonly relapse, resuming at their old volume rather than rebuilding. A physiotherapist can guide the specifics for your case.
When it might be something more serious (important)
This deserves a clear warning, because it's the part that matters most. Shin pain can also be caused by a stress fracture or, less commonly, compartment syndrome — and these need different management. Features that warrant prompt professional assessment include: sharp, pinpoint pain on a specific small spot of bone (rather than diffuse along a stretch), pain that persists at rest or at night, pain that worsens despite reduced activity, pain when hopping on that leg, or numbness, tingling, or severe tightness with exertion. Honest advice: don't self-diagnose shin pain as "just shin splints" and keep running through it — a missed stress fracture is a considerably worse problem.
Reducing your risk (prevention that actually helps)
Since it's primarily a load problem, prevention is primarily load management. Increase running volume gradually — the roughly 10% per week guidance in how to run longer exists precisely because bone and connective tissue adapt slower than your cardiovascular fitness improves. Build back gradually after breaks rather than resuming where you left off. Strengthen calves and hips to increase your capacity to absorb load. Check your cadence — increasing a low cadence reduces impact per step (see running cadence). Replace worn shoes and avoid sudden surface changes. And take down weeks rather than building relentlessly.
Quick answers
What are shin splints?
Commonly medial tibial stress syndrome — diffuse pain along the inner shin from tissue being loaded faster than it can adapt.
What causes shin splints?
Usually training load increasing too quickly, plus contributors like weak calves and hips, low cadence, worn shoes, and hard surfaces.
How long do shin splints take to heal?
Typically weeks, varying considerably — professional guidance helps set realistic expectations.
Should I stop running completely?
Often load reduction rather than total rest, with low-impact cross-training — but this depends on severity, so get it assessed.
Can I run through shin splints?
Not advisable — continuing to load it can worsen the problem and delay recovery.
How do I know it's not a stress fracture?
Sharp pinpoint pain, night pain, or pain when hopping are warning signs needing prompt assessment — you can't reliably tell on your own.
How do I prevent them?
Increase mileage gradually, strengthen calves and hips, check cadence and shoes, and take down weeks.
Shin splints aren't a stretching problem or a shoe problem. They're a "you added mileage faster than your shin bone could adapt" problem — which is also why the fix is patience.
Shin splints are fundamentally an overload injury: tissue asked to do more than it was ready for. Management means reducing load, maintaining fitness with low-impact work, strengthening the calves and hips, and returning gradually. Above all, don't assume all shin pain is shin splints — pinpoint pain, night pain, or worsening symptoms deserve prompt professional assessment.
