Night Sweats anyone? No thanks Legz, you can keep them. LOL
I don't have that issue. It could be from the Avonex, your surgery, or the menopausal issues you are having or even a combination of the 3. However, I would mention it to your dr the next time you go as it could be something else.
BTW - I do know that when I am really sick I occasionally get night sweats. In fact, I am trying to get over a sinus infection. I don't want to do another round of abx so I started doing my Neti faithfully. Yesterday I woke up from my nap sweaty - not soaked or anything like that, just sweaty. I am assuming this was a good sign that I am breaking through the infection.
I hope you start feeling better soon.
