Doctor's Notes on Shin Splints

"Shin splints" (medically termed Medial Tibial Stress Syndrome, or MTSS) describes a running-related injury that causes pain in the front of the lower leg along the shin bone (tibia). Pain from shin splints is usually caused by athletic-related activity that the participant is not physically prepared to perform.

The main symptom of shin splints is pain on the lower third of the shinbone or the tibial bone, furthest from the knee. There are four grades to the pain of shin splints: 1) during activity, 2) before and after activity, but not affecting performance, 3) before, during, and after athletic activity affecting performance, and 4) pain so severe that performance is impossible. Other symptoms of shin splints include a distinguishable lump or gap felt on the lower third of the shinbone, or a "crunchy" feeling on that spot caused by inflammation.
