Julie - It's been my experience that the low grade fevers come from active disease. The night sweats are a common side effect of pred. When I was on it, I often woke up drenched. However, since I've been off of it, I haven't had that symptom. My fibro flares often and doesn't necessarily cause a crohn's or arthirits flare. However, when my crohn's flares, the fibro acts up pretty badly. My skin, hair, even the bottoms of my thighs when I sit and bottom of my feet when I walk hurt me. Sorry you feel bad - I know how uncomfortable it is.
It's hard for my peers and family to understand this pain. They express concern, but I can tell in their eyes that they have no idea what I'm going through.
We'll get through this together.
