Myofascial pain syndrome is a chronic pain disorder. In this condition, pressure on sensitive points in your muscles (trigger points) causes pain in the muscle and sometimes can cause pain spread to other  parts of your body. This is called referred pain. Trigger points can also cause stiffness and weakness.
This syndrome typically occurs after a muscle has been contracted repetitively. This can be caused by repetitive motions used in jobs or hobbies or by stress-related muscle tension.
While nearly everyone has experienced muscle tension pain, the discomfort associated with myofascial pain syndrome persists or worsens. Treatment options include massage therapy, dry needling, and physical therapy. relaxation techniques such as meditation also can help.
