I'm sorry you're not feeling well. When I had a cold or flu whatever it was, I called my rheumy who said if my fever gets to 101 or higher then to go to the ER. After a day, my fever went away so I never had to go to the ER. Guess since I was on Imuran my immune system was compromised so it's easy to get sick. Anyway, I hope you get better soon! Get lots of rest.
