I had one doctor say I might have fibromyalgia but they weren’t willing to label it. It was one of those docs who write things like “patient alleges fatigue” and appears to complain of possible brain fog. Like they don’t believe me about my own feelings and ability to think clearly lol. I was shaking my head reading that docs medical file on me. I had to switch for a move from NY to WA state. None of my more recent doctors have brought it up and I always hesitate to bring specific labels up to them because it looks like I’m trying to google diagnose myself. That said it might be fibromyalgia. Is it’s not MS and autoimmune it would clearly make sence to my non doctoral holding brain. But who knows. Thanks for letting me know your experiences it helps to hear.
