Shin splints: causes, recovery time and getting back to running

What are shin splints?

"Shin splints" is the everyday name for pain along the inner edge of the shin bone, known medically as medial tibial stress syndrome. The pain usually spreads over several centimetres along the lower half of the shin, is tender to press, and comes on with running or jumping. Early on it may ease once you are warmed up and return afterwards; later it can hurt throughout a run and even when walking.

It is thought to be an overload reaction in the bone and the tissue that covers it, where the calf muscles attach, rather than a single injury. Our shin splints page covers the condition itself; this guide focuses on recovery and getting back to running.

Why it happens

Shin splints are, above all, a training-load problem. The bone adapts to running by becoming stronger, but that takes time; when load rises faster than the bone can adapt, it becomes irritated. Common triggers include:

• a sudden increase in mileage, pace or hill work, or starting running from scratch
• a switch to harder surfaces or to new or worn-out shoes
• more sessions without enough recovery days between them
• lower-limb factors such as flat or rolling-in feet, limited ankle movement or weak calf and hip muscles
• being new to impact sport, or returning after a long break

Women, and anyone with low energy availability, low bone density or a previous stress injury, may be more susceptible.

Is it a stress fracture?

A stress fracture of the tibia is a related but more serious bone injury, and it is important not to run through it. Features that raise concern include:

• pain in one small spot on the shin, rather than spread along it, and very tender to press at that point
• pain that comes on earlier in each run, persists after stopping, or hurts when walking, at rest or at night
• pain when hopping on the affected leg
• a history of previous stress fractures, missed periods or low bone density

If any of these apply, call us for a same-day assessment. We can examine you and arrange fast-track X-ray or MRI through our imaging partner, often with same- or next-day appointments subject to availability. An early X-ray can be normal in a stress fracture, so MRI is sometimes needed. Go straight to A&E for more severe symptoms, such as a sudden crack with inability to bear weight after a fall or impact, or an obvious deformity.

How long does recovery take?

For straightforward shin splints, many people are running comfortably again within a few weeks to two or three months, depending on how long the pain has been there and how early they adjust their training. Long-standing cases tend to take longer. A stress fracture usually needs a period of reduced loading of around six to eight weeks or more, guided by your clinician, before a gradual return. These are typical ranges, not promises — recovery varies between people.

What to do while it settles

• Reduce impact, keep fitness. Stop or sharply cut back running for a period and swap in cycling, swimming, deep-water running or the cross-trainer, which keep your fitness without loading the shin.
• Strengthen the calf and foot. Calf raises (both bent- and straight-knee), toe curls and single-leg balance work may help the lower leg tolerate load. Build up gradually.
• Strengthen the hips. Side-lying leg raises, bridges and step-ups help control the leg during running.
• Review footwear. Replace worn shoes. Where foot posture seems to be a factor, a 3D foot scan can show whether custom orthotics may help spread the load.
• Ice and over-the-counter options. A cold pack for 10–15 minutes after activity may ease soreness. Ask a pharmacist about over-the-counter pain relief if needed.
• Look after the basics. Sleep, enough food for your training, and adequate calcium and vitamin D all support bone health.

Getting back to running

Return gradually once walking has been comfortable for at least a week or two and hopping on the leg is comfortable. A sensible pattern:

• Start with run–walk sessions on a soft, flat surface — for example one minute of easy running and one minute of walking, repeated for 15–20 minutes.
• Run every other day, not consecutive days, so the bone can adapt.
• Increase total weekly running by no more than around 10 per cent at a time, and change only one thing at once: distance before pace, pace before hills.
• Mild discomfort that settles within 24 hours is usually acceptable; pain that is increasing, or still there the next morning, means stepping back a stage.
• Keep the strength work going after you are back; it is part of staying well.

Physiotherapy can help with a structured return plan, hands-on treatment for tight calves, taping, and, for long-standing cases, focused shockwave may be discussed. Outcomes vary from person to person, and fees are on our fees page.

When to book

If shin pain has not started to improve after two to three weeks of reduced running, keeps coming back when you build up, or you are unsure whether it could be a stress fracture, an initial assessment at our Bloomsbury clinic is a sensible next step. We will examine your leg, explain what we find and agree a return-to-running plan with you.
