Medical Conditions - Hamstring

The hamstring comprises three muscles on the back of the thigh: the biceps femoris, semimembranosus, and semitendinosus. These muscles originate from a bony protuberance in the pelvis and extend down to the lower leg. They are important muscles to perform daily activities like running, jumping, and climbing. Injury to the hamstring muscles can cause pain, swelling, bruising, and weakness in the back of the thigh. Stretching and strengthening exercises and avoiding overexertion can prevent such injuries.
