Pain that develops in the inner thigh may be accompanied by muscle stiffness, limited range of motion, and inflammation. Because the adductor muscles of the inner thigh are close to the groin, the pain may also be felt in the region of the hip between the stomach and thigh. Common causes of inner thigh pain are strains (or tears) of the adductors, which may arise from activities such as running or turning too quickly. The intensity of pain varies in accordance with the severity to which the muscle has been damaged. In some cases, the pain can be accompanied by bruising and swelling. In any case, it is important to have the cause of inner thigh pain correctly diagnosed.
