By Mayo Clinic Staff. Hip pain is a common complaint that can be caused by a wide variety of problems. The precise location of your hip pain can provide valuable clues about the underlying cause. Problems within the hip joint itself tend to result in pain on the inside of your hip or your groin. Hip pain on the outside of your hip, upper thigh or outer buttock is usually caused by problems with muscles, ligaments, tendons and other soft tissues that surround your hip joint. Hip pain can sometimes be caused by diseases and conditions in other areas of your body, such as your lower back.
What causes hip pain? Most hip pain has a very simple explanation, for example if youâve overdone it while exercising. The pain is usually caused by strained or inflamed soft tissues such as tendons, and it often clears up within a few days. Long-term hip pain can be caused by specific conditions. Pain caused by a problem in the hip joint can be felt in the groin, down the front of the leg and in the knee. Sometimes knee pain is the only sign of a hip problem. This is called referred pain, and itâs fairly common. Hip pain can also be felt in the buttock (although pain in this area can also be caused by problems with the lower back) or on the outside of the hip.
