Does anyone have anything on why night sweats occur or what to do about them. I usually wake up with my upper body wet if not drenched. It started happening after I was doing some neck stretches. Oddly enough they triggered a bizarre array of symptoms - nausea, fatigue, MCS, went way up, nightsweats..... It took me months to figure out that those stretches were it. I asked Dr. Perrin about it -he said something was going on with my neck (no doubt) - that general area is where he thinks alot of our problems are. Somewhere I tweaked something in there. Anyway the flareup died but here I am two years later and I'm getting nightsweats regularly. Anybody have a handle on them?
