Hello Everyone, I would like to ask a question and get your feedback. Like many of you, I have been told many different things by different doctors. I have been told I have atypical ME/CFS but here is the confusing part. I was also told that the fatigue had to pre-date all other symptoms. In my case, the brain fatigue came last. Has anyone else had the fatigue happen after other symptoms had already occured? Thanks so much for your help.
