What are the symptoms of shin splints?
The NHS describes the main symptom as pain and tenderness along the front of your lower leg, usually coming on during exercise such as running. The pain of medial tibial stress syndrome typically runs along the inner edge of the shin bone, over a stretch of several centimetres, and it tends to ease when you stop and return with the next run.
That spread matters. Pain along a length of bone behaves differently from pain in one small spot, which is the first thing a clinician checks, as the section on stress fractures below explains. If you run, the Achilles tendinopathy and plantar fasciitis pages cover the other two lower-leg problems that most often bring runners to shockwave.
