Hi Bill! Welcome! I was diagnosed at 55 after many years of extreme symptoms. The team of doctors at a University Hospital told me I may have had this since I was eight -experiencing hypothermia then, although auto immune issues definitely run in my family. I have 3-6 “episodes” a year, when I was younger many more and a few years it was constant. I have learned what I can eat and do. Stress and lack of sleep or rest being a major factors. A positive attitude essential and constant awareness of what you need to do to feel as best as you can. When episodic medical help almost always essential. Finding your triggers is so important. I’ve done the elimination diet several times with much success. Best of luck and health! Ask any questions you need to!
