Almost 90% of the population suffers from neck or shoulder pain due to stresses of modern life. Repetitive strain injury is a common cause of pain in tendons, nerves, and muscles from continuous or overuse movement. Poor posture during physical activity can also strain neck and shoulder muscles. Sports massage therapy can help athletes and others by focusing on stressed and overused areas to provide relief to muscles and tendons. Trapped nerves in the neck, known as cervical radiculopathy, can cause shoulder pain when nerves are compressed.
