Myofascial trigger points are contracted knots that form in muscle tissue. They form from overload stress placed on the muscle. Both chronic stress such as poor posture and acute stress such as an injury will cause trigger points to form. Once there a trigger point will produce pain, referred pain, weakness and stiffness. Trigger points don’t go away with rest or with time, some form of intervention such as trigger point massage is needed to treat the injured muscles. Trigger points can form in any muscle in the body and are one of the most common causes of pain.
