Trigger points are small sites of tight muscles. Myofascial pain syndrome (MPS) is when pressure on trigger points results in pain in other parts of the body.
The cause is not clear.
Trigger points causes are:
Injury, such as to discs in between the spinal bones
Emotional stress or tension
The trigger point can stay even after the cause of it has healed.
MPS may be more common in women.
MPS may cause:
Muscle pain or weakness
Pain in parts of the body other than the trigger point
A feeling of pins and needles
The doctor will ask about your symptoms and health history. A physical exam will be done. It will focus on areas of pain. The doctor may diagnose you based on your symptoms and whether you have trigger points.
