I wonder if these massive chills are part of the crohns and not the meds. Back about a year ago I had a small fever but chills so bad I could not walk...literally could not walk. I could not sleep so i was up atthe computer very late (1 or 2 AM) I started to get chilled and then just started shaking so bad I tried to walk to the shower and could not stand up...I crawled, actually dragged my body using only my arms into the bathroom...I tried to call for my wife, but could not get my voice above a very hoarse whisper. I made it into the shower and started a very hot shower (now been told hot showers are a bad thing for the chills). After about 30 minutes my legs started to get feeling back in them and I fell into our bed exhausted. This happened again for the next two days and nights....and one night I woke up and tried to get out of bed....no chills but my entire lower body was without any feeling and would not work...I collapsed to the floor. The doctors could not find any cause...no infection....very low fever for just one of the days....NOTHING!!!!
I was not on any meds at the time so that could not have been the cause.....but now I read where so many of us have had these major chills and makes me wonder.
