Shin splints often occur in athletes when they start training harder or longer. The increased activity puts stress on the muscles, tendons and bone tissue.

Shin splints might cause tenderness, soreness or pain along the inner side of the shinbone and mild swelling in the lower leg. At first, the pain might stop when exercising stops. It might feel better with stretching. But in time, the pain can be ongoing. That could mean a stress reaction or a stress fracture.

Most often, shin splints get better with simple self-care steps. They include rest, ice and pain relievers.
