What should you know about reason for shin splints?

A sudden increase in running, jumping, hills, or training days can leave the muscles and the bone covering unable to adapt to the new demand. Hard or uneven surfaces, worn footwear, and limited calf or ankle mobility may add stress. Flat feet can change how the lower leg absorbs force; learn more about [Flat Feet](/conditions/flat-feet/). The discomfort is often spread along the inner border of the shin rather than confined to one tiny spot. [Shin Pain](/symptoms/shin-pain/) can have other causes, so the pattern and activity trigger matter.

Reduce or pause the activity that provokes pain, while choosing lower-impact movement if it remains comfortable. Ice wrapped in cloth may settle soreness after activity. Resume gradually when everyday walking is comfortable, with shorter sessions and rest between them. A clinician or physiotherapist can review footwear, calf strength, ankle motion, and running form. [Gait Retraining](/treatments/physiotherapy-and-rehabilitation/gait-retraining/) and [Physiotherapy](/treatments/physiotherapy-and-rehabilitation/physiotherapy/) may help address load and movement; [Custom Orthotics](/treatments/non-surgical-orthopedics/custom-orthotics/) can be considered when foot mechanics are contributing.

Arrange an assessment if pain is worsening, persists despite reducing impact, alters your walking, or becomes focused in one small area. Seek prompt care after significant trauma, or when swelling, numbness, weakness, marked redness, fever, or pain at rest appears. A clinician can distinguish shin splints from a bone stress injury or another source of shin pain.

Could my training change, foot shape, footwear, or running pattern be contributing? What activity can I safely continue? Which findings would make imaging or a different diagnosis necessary?
