Shin splints is a condition characterized by inflammation of the muscles, tendons, and bone tissue around the tibia, or shinbone. Shin splints cause pain that typically occurs along the inner edge of the shinbone, where muscles attach to the bone. Shin splints are caused by exercise or repetitive activity and often occur after changes in the intensity of activity, such as running for longer times or distances. Certain conditions can increase the risk of developing shin splints, including flat feet, high arches, and improper or poorly fitting shoes.
