Thigh Pain (Definition) The thigh is the upper part of your lower extremity between your hip and knee. Any pain within this region could be considered thigh pain. Possible diagnosis include fractures, stress fractures, muscle contusions or strains, referred pain from the back and hip to name only a few.
Anatomically, it is part of the lower limb. The single bone in the thigh is called the femur. This bone is very thick and strong (due to the high proportion of cortical bone), and forms a ball and socket joint at the hip, and a modified hinge joint at the knee.
