The most common cause of shin pain is shin splints, an overuse condition that is particularly common in runners and other athletes. It often involves small tears in the muscles where they attach to the surface of the shin bone; the resulting inflammation is called Periostitis. Foot structure (flat feet or extremely high arches) and incorrect foot wear or worn out shoes can make you more likely to develop shin splints.
If you experience shin pain it is important to determine what the cause is, and treat it accordingly. If it is not corrected the problem may become chronic and lead to stopping activities completely due to the pain involved.
