I found this 'sweating' topic interesting as I have asked on forums before if anyone gets the pain/sweating/nausea and have never had a reply - so I presumed no one did!
I get it and it is horrible isn't it, I get anxiety and fatigue with it too. I don't sweat profusely I guess, though have done so at night, I have a fan next to my bed.
I haven't any solutions to offer, I am guessing that which ever part of the body regulates the temperature is being affected by bacteria, or it could be one of the ways our bodies are trying to get the toxins out.
I wish I had some constructive advise to offer . Best Wishes .
