When joints are forced beyond a normal range of movement, ligaments stretch and tear. Strengthening of surrounding muscle groups is crucial. A subluxation is an incomplete or partial dislocation of a joint. Tendinitis and bursitis are the most common musculoskeletal conditions. Tendinitis is inflammation of a muscle tendon.
Tendons lie at the ends of muscles where they attach to bones.
Acute or chronic pain occurs with movement of the muscle or joint if a tendon is inflamed. The inflammation of a bursa is called bursitis. Bursas surround joints and muscle tendons. Bursas are a sac-like cavity filled with fluid. They guide and lubricate the muscles and joints, which enables a muscle or tendon to slide over bone.
