This video is very informative, insightful as well as validating that FM is not psychological. The physician, Patrick W. Wood MD, Pacific Rheumatology Associates, Chief Medical Officer Angler Biomedical Technologies, uses clear understandable language, hence IF WILLING, capitalization deliberate, would be useful for family, friends and the general public. It was made five years ago. I would love finding updates about this guy's research as well as the other research he mentions. The video is in three parts. While the third part is interesting, for practical purposes, you could probably skip it. Edit. After watching part three, I would recommend at least the first part as that's where he talks about opiates and something else but can't remember what. BUT, ignore the very last patient case. Fortunately, he says this happened in this particular case but not the best example to use. Some of his topics I found particularly interesting as they pertain to me are: Why opiates often don't work for FM patients. The link between FM and Willis-Ekbom disease, RLS, also known as restless legs syndrome as both are dopamine related. The link between low ferritin levels and pain. My personal favorite, paraphrased here, "If your doctor says FM is not real, get in his or her face, laugh and get another doctor!". I would think some of this would be applicable to me/cfs which he mentions as a comorbid condition. He uses this term. Barb ETA One caveat to remember is that while brain scans are informative, you can’t expect to look at one without knowing the patient's condition, and give a definitive diagnosis.
