I don't think its anything neuro-related. I know all doctors have told me it can even be from tight muscles, and you know how tense we can get when in a flare. Prednisone probably doesn't help either.
Symptoms are better today, hoping they stay that way now that I'll be on 30mg of Pred for another week. I'm actually excited to start taking my Imuran again! I guess, if anything, getting the 'flu' and having to stop the Imuran, plus getting UC symptoms again, made me really just want to do anything to get better. So now I am looking forward to trying the Imuran and hoping its the key to remission rather than being as scared to take it like I was before! :)
