lateral
posterior

what is the difference between shin splints and compartment syndrome
During a physical exam for exercise-induced compartment syndrome, the affected area usually feels normal, without tenderness to palpation. In contrast, a physical exam for shin splints or stress fracture will often demonstrate tenderness over the bone or fascia.
