What should you know about left shin splints?

Shin splints develop when the tissues around the shin are exposed to more repetitive load than they can currently tolerate. Pain is often spread along the inner border of the left shin and may start during or after running, jumping, marching or a sudden increase in activity. Stiff calves, a change in surface or footwear, and foot mechanics such as flat feet may contribute, but no single factor explains every case.

The pattern should be checked if pain becomes pinpoint, appears at rest, causes marked swelling or changes your walking. Shin splints and a stress fracture can overlap in early symptoms, so worsening or localised pain should not be labelled as shin splints without assessment.

Reduce impact, hills and sudden training increases while pain settles. Keep a symptom-free alternative such as easy cycling or swimming only if it does not provoke symptoms. Check that shoes are supportive and replace worn footwear. Gentle calf mobility and a gradual strengthening programme can improve tolerance; avoid aggressive stretching into pain.

[Physiotherapy](/treatments/physiotherapy-and-rehabilitation/physiotherapy/) can assess loading, calf strength and movement. [Gait Retraining](/treatments/physiotherapy-and-rehabilitation/gait-retraining/) may help adjust running or walking technique, while [Custom Orthotics](/treatments/non-surgical-orthopedics/custom-orthotics/) may be discussed when foot mechanics are part of the problem. Return to impact gradually when ordinary walking is comfortable.

Arrange assessment if pain is pinpoint, persists despite reducing impact, returns quickly with easy activity or makes you limp. Seek urgent care after trauma with inability to bear weight, significant swelling, deformity, or numbness or colour change in the foot. Pain at rest or at night deserves prompt review because it does not fit a simple training-related pattern.

Ask whether the tenderness is diffuse or focal, whether a stress injury needs excluding, and which activities you can continue. Ask about calf and hip strength, running form, foot posture, footwear, orthotics and a staged return-to-training plan.
