Hamstring strains can occur during any strenuous exercise, as well as from overuse, and they are very painful injuries. The hamstring is a group of muscles that runs down the back of the upper leg, and helps you to bend your knees. Hamstring strains occur when these muscles tear, which can occur suddenly or gradually during the course of an activity. Properly warming up can help prevent hamstring injuries, but they are still very common, especially among athletes. It is important to know the symptoms of hamstring strains, as well as how to treat them.
