I have been trying to taper off prednisone from a colitis flare up. it has been horrible and my joints have become so sore every time i hit the 10 mg?

Medications: Are you on any other medications for your colitis. If you are having trouble coming off steroids then medications like Remicade (infliximab) and Humira might help.

Other meds? : If you have severe enough crohns disease that it requires prednisone, it is unlikely that you will be able to just taper off without the use of a steroid sparing agent such as biological agents (ie. Remicade) or immunomodulators (mercaptopurine). See your gastroenterologist or am did a referral to an ibd subspecialist.
