Apart from when hip pain is caused by a specific injury or an arthritic hip joint, most pains in the hip or top of the leg are caused by a mechanical overload from a problem elsewhere. This will usually be from the lower back or pelvis but can be from the knee or even the foot. Recurring groin strains are common in sportspeople, especially footballers, and a twisted pelvis is often the root problem, which causes weakness and an overload of the muscles and tendons around the hip.
Pain in this area often makes walking very difficult and patients often “seize up” if they have been sitting for too long. If a chronic hip problem is not treated it can cause problems with the lower back as the patients start to adapt the way they walk.
