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.
Pain in the hip can result from a number of factors. Abnormalities of the skin, nerves, bones, joints, blood vessels, and soft tissues of the hip can all result in pain. Sometimes diseases that affect other joints in the body, such as the inflammation resulting from arthritis, can be the cause of pain in the hip.rauma or injury, including bone fracture, is also a cause of hip pain. Pain in the hip area may also originate from painful infections or other conditions of the skin, such as shingles.
