What should you know about posteromedial shin splint?

The posteromedial border is the inner and back side of the tibia. Shin splint symptoms there may feel achy, tender, or tight during and after impact activity. Running, marching, jumping, long walks, and hard surfaces can increase the load on the calf and tissues attached to the shin. Flat feet or an inward-rolling foot may contribute to altered loading, although they are not the only possible factors. Broad tenderness along the border is more consistent with an overload pattern than one sharply defined spot. Focal tenderness, pain with ordinary walking, or discomfort at rest should be assessed for another cause such as bone stress.

Stop or scale back the activity that raises symptoms, then use comfortable low-impact exercise to maintain general movement. Avoid sudden increases in distance, hills, speed, or jumping. When daily walking is comfortable, rebuild gradually and include calf, foot, and hip strengthening as advised. A physiotherapist can examine ankle mobility, muscle capacity, foot posture, and gait. Gait retraining or custom orthotics may help selected people when assessment identifies a modifiable loading pattern. Shoes should feel supportive and appropriate for the activity rather than being changed repeatedly without a clear reason.

Arrange a clinical review when pain persists despite reduced activity, repeatedly returns with gentle exercise, or changes how you walk. Seek prompt assessment for one precise tender point, swelling, pain at night, or pain while resting. Urgent care is appropriate for severe lower-leg pain with increasing tightness, numbness, weakness, or a cold or pale foot. These features can signal a problem requiring timely examination and are not a reason to push through training.

Ask whether your tenderness is diffuse or focused, whether imaging is needed, and which activities are safe while symptoms settle. Ask if foot posture, gait, footwear, calf strength, or ankle flexibility is contributing. Request clear criteria for progressing from walking to jogging and from jogging to normal training.
