Three different muscles make up the hamstring group and are responsible for extending the hip and bending or flexing the knee. Muscle knots in the hamstrings, which are located in the back of the thigh, can cause pain in the back of the thigh but additionally may cause pain in the buttocks area and the lower leg. Tight hamstrings can also cause lower back pain.
Hamstring muscle knots, which consist of tight and contracted muscles, are indicated below by a black dot. The red area in the illustrations indicates “referred pain” – meaning, the pain you feel is often not in the location of your trigger point until you press on it. As an example, you may have a dull ache behind the knee, but the trigger point may actually be in the hamstrings.
