Will guaifenesin work for myofascial pain syndrome (MPS) and chronic fatigue syndrome (CFS)?
Yes. Dr. St. Amand says they’re similiar to Fibromyalgia, and many other doctors these days agree. The diagnosis depends on the first symptoms you went to the doctor with. If your major complaint was pain, you were probably told you had MPS; if your major complaint was fatigue, you were probably told you had CFS. We think that patients with a higher pain threshold have more fatigue and less pain; patients in the middle have a mix of both, and some patients, with a lower pain threshold have mostly pain, but are tired too. However, pain is a poorly understood, very subjective phenomenon, so we do not have a good understanding of its many variations from person to person. Trigger points and tender points will go away with Guaifenesin. Dr. St. Amand believes myofascial pain is part of FMS, and that the tendons and tendon sheaths it affects take longer to clear than muscles, because they have less blood flow. But they will clear up. He has agreed to disagree with Dr. Devin Starlanyl on this
