Myofascial pain syndrome (MPS) refers to pain and presumed inflammation in the body's soft tissues or muscles. It is a condition of muscle pain. It is a chronic, painful condition that affects the fascia (connective tissue that covers the muscles). It could involve either a single muscle or a muscle group. The main complaint is muscle pain. The pain can be deep, aching pain in a muscle and it can persist or worsen with activity or stress. It can affect one’s sleep. Examination can find trigger points in related muscles and a tender knot in a muscle. The causes include a muscle injury, strain on a muscle, ligament or tendon, disks problem, chronic fatigue, repetitive movement, lack of activities, some medical conditions. Muscle tightness creates trigger points in the muscles. An acute muscle injury or continual muscle stress may lead to the development of trigger points. People who frequently experience stress and anxiety may be more likely to develop trigger points in their muscles.
There are four types of trigger points
An active trigger point is an area of extreme tenderness that usually lies within the skeletal muscle and which is associated with a local or regional pain.
A latent trigger point is a dormant (inactive) area that has the potential to act like a trigger point. It may cause muscle weakness or restriction of movement.
A secondary trigger point is a highly irritable spot in a muscle that can become active due to a trigger point and muscular overload in another muscle.
A satellite myofascial point is a highly irritable spot in a muscle that becomes inactive because the muscle is in the region of another trigger pain.
Acupuncture can reduce myofascial pain effectively by releasing muscle tension and removing trigger points in the muscles.
