What should you know about posterior shin pain?

Pain behind the shin can be felt along the calf-side border of the lower leg or close to the ankle. It may appear after running, jumping, hill walking, a change in training, or prolonged standing. Muscle soreness is often spread through the calf and linked to movement, while a stress injury may cause more focused tenderness that persists with ordinary activity. Swelling, warmth, bruising, numbness, or weakness changes the picture and deserves clinical attention. Posterior shin pain is a symptom, not a diagnosis; an examination helps distinguish soft-tissue overload from problems involving the bone or circulation.

Reduce or pause the activity that clearly brings on the pain, while keeping gentle, comfortable movement if it does not increase symptoms. Support the leg when resting and use a cool pack wrapped in cloth for short periods if that feels soothing. Avoid deep massage directly over a sharply tender area. When walking is comfortable, return gradually with easier sessions, level ground, and a slower increase in workload. A physiotherapist can review calf strength, ankle movement, footwear, and running mechanics, then tailor loading exercises.

Arrange an assessment if pain is pinpointed over the bone, continues at rest or at night, returns whenever you resume activity, or does not settle after reducing the provoking load. Seek urgent help for sudden severe pain with a tight or swollen lower leg, a cold or pale foot, new weakness or numbness, or marked one-sided calf swelling with breathlessness or chest pain. A clinician may examine your gait and leg, and decide whether imaging or other tests are appropriate when a stress injury is suspected.

Ask: Which structure seems to be causing the pain? Should I stop running or choose a lower-impact option? What signs would make a stress injury more likely? Which exercises can I start safely, and how should I increase them? Do my footwear, training surface, or ankle movement need review?
