I'm having low body temp with any activity, and daily pain even with excercise what gives?

I have RRMS my question is maybe it's denial, I'm not sure, I feel pain everyday, I do my core exercises, stretching, and pilates for MS at times I have to force my self do to the fatigue. I thought by doing these it should make me feel better, I seem to have one maybe two days of feeling okay, however the pain and fatigue is ever present. Lately after my sinus infection. I'm having low body temp and increased sweating with any activity. My PCP said it could be an infection, but all results were normal, I was told to grin and bear it. 93.4-94.6 seems low for me I'm normally 97.7, but since using Copaxone I was 96.7. I'm on Avonex now I was told it's not a side effect of that medication. I just had a recent flare up on 8/4/09 could it still be a result of that flare up.

Dazed and Confused.
