Fibromyalgia is a syndrome that does not have a clear explanation, being this the name given to the condition of some people to suffer muscular pain in any part of the body constantly. On the other hand, myofascial pain syndrome is used to diagnose pain caused by fibromyalgia.
So far, due to the little study that revolves around trigger points and muscle pain, there is no clear difference in either causes or symptoms between fibromyalgia and myofascial pain syndrome.
