Anyone know if excessive sweating is a symptom of CFS or fibromyalgia? Been diagnosed 4 years ago and thought it was from medication, stopped all meds and still having problems! Don't even need to move and I sweat. No periods for over 2 years so don't think its menopausal?? Got a prolapse but GP says it not caused from that! Had thyroid tests which came back normal even though have many symptoms. Also what meds are people on that are working for them? I came off tapentadol, Venlaflaxine and zopiclone as I thought sweating was caused by one or all of them, but still suffering. Tried iodine for 2 weeks from naturopath and surprise surprise all symptoms disappeared. Fed up with feeling in pain and sweating.
