A condition in which pressure on the brachial plexus causes pain in the arms and shoulders, pins-and-needles sensation in the fingers, and weakness of grip and other hand movements. Severe symptoms are usually caused by a cervical rib. Thoracic outlet syndrome may also be caused by drooping of the shoulders, an enlarged scalenus muscle in the neck, or a tumour. The condition is made worse by lifting and carrying heavy loads or by increases in body weight. Treatment of thoracic outlet syndrome usually consists of exercises to improve posture, sometimes together with nonsteroidal anti-inflammatory drugs and muscle-relaxant drugs. Severe cases may be treated by surgical removal of the 1st rib.
