Like fibromyalgia, Myofascial Pain syndrome is an often misunderstood condition. Even today, some doctors either don't believe that MPS exists or they don't understand its symptoms and treatment. Treatment of MPS can only begin after an accurate diagnosis is accomplished. Methods for managing this painful condition: 
Trigger Point Therapy {Myofascial release therapy, myotherapy, massotherapy (medical massage therapy), Spray and Stretch technique (stretching of the muscles involved with a vapocoolant spray - a coolant is sprayed on the trigger point to lessen the pain and then the muscle is stretched. this is often done by a physical therapist.),  Trigger Point Injections (local anesthetic,such as lidocaine, injected directly into the trigger points), Dry Needling (the use of a needle without injecting anything) [TrP injections and dry needling mechanically disrupt the tirgger point. The use of lidocaine is no more effective, but it reduces the soreness after injection. For MPS there is no role for injected steroids], Chiropractic or Osteopathic manipulation treatment, Craniosacral Therapy, Physical Therapy (hands-on), Exercise, Improvement of nutrition, Changing sleeping habits, The use of tricyclic antidepressants in low doses, Elimination of stress; Biofeedback; Counseling for depression that may result from this painful condition.

   An active trigger point when treated well or with rest will become latent (quiet, or not causing active symptoms). It can often resurface after trauma after acute overload or fatigue, or even sudden exposure to cold. Conversely, new trigger points may arise elsewhere, or at least become more sinificant as others become latent. For MPS, you should see a doctor knowledgeable in chronic pain such as a physical medicine doctor (a physiatrist), or a neurologist.

   The diagnosis is made by the history and physical exam. There is no lab test nor imaging studies to confirm the diagnosis. A history of acute trauma or chronic overuse should be looked for.. On exam, there is typically restricted motion with pain of the affected muscle. Other medical problems need to be ruled out with imaging or other studies. For instance, if a patient presents with back pain, disc and other problems need to be ruled out.

   Altered Pain Perception Accompanies MPS: A Danish study indicates that people with chronic myofascial pain perceive and transmit pain differently than people without the syndrome. As many as 72 percent of people with fibromyalgia may have trigger points associated with myofascial pain. Source: "Qualitatively altered nociception in chronic myofascial pain," by L. Bendtsen, R.
