Groin pain usually presents as a localised pain which can radiate into the thigh or hip, preventing full hip extension on running or walking.
Usually, as a result of a sports injury or sudden forced extension of the hip, the muscle in the groin spasms and becomes inflamed. This in turn irritates the local nerves causing pain to refer into the leg and hip. In some cases local swelling of the muscle can be a feature. Spasm is a shortening of the muscle and certain movements need the muscle to stretch and lengthen. These movements become difficult and produce acute pain if the movement is pushed to its full range. An underlying reason behind groin pain can be related to a mechanical imbalance in the pelvis and low back as well as tightness of the hamstrings.
Treatment aims to break the spasm and reduce inflammation. Examining the legs, low back and pelvic mechanics and treating any underlying imbalances prevents any future problems.
