Pain in the back of the thigh (hamstring pain)
Pain in the back of the thigh, also known as hamstring pain, is a common problem that can affect people of all ages. The hamstring muscles consist of three main muscles that enable movements such as bending the knee and extending the hip. Causes of hamstring pain are varied and can include muscle strains, overuse from sports activities, tendonitis and injuries such as muscle fiber tears. Symptoms often include pain in the back of the thigh, which can radiate to the buttocks or the back of the knee, as well as stiffness and limited mobility.
