Definition
Hip pain is a common complaint that can be caused by a wide variety of problems. The precise location of hip pain can provide clues about the underlying cause.
Problems within the hip joint itself tend to result in pain on the inside of the hip or the groin. Hip pain on the outside of the hip, upper thigh or outer buttock is usually caused by problems with muscles, ligaments, tendons and other soft tissues that surround the hip joint.
Hip pain can sometimes be caused by diseases and conditions in other areas of the body, such as the lower back. This type of pain is called referred pain.
