Shin Splints in Runners

Shin splints — clinically known as medial tibial stress syndrome (MTSS) — is an overuse injury where the connective tissue and bone along the inner edge of the tibia become inflamed and tender. It sits on a continuum: pushed too far, MTSS becomes a tibial stress reaction, then a true stress fracture.
