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.
Form and Function. Your thigh muscles are connected by layers of fascia that connect to the muscles in your hip, back and lower leg, according to Myers. They work with the hip to produce locomotion for walking and climbing, and to stabilize your leg and pelvis when you stand and move.
