PredniSONE and servere

I was on Pred for about 9 months(FSG Kidney Disease) and came off about 3 weeks ago. The problem that I have been having for the past three weeks is moderate to servere pain in my joints and muscles? This includes area's like my feet, shoulders, knees and chest. How long should these problems persist? The only thing gettying me by now are pain killers.

I was taking the Prednisone pack for a servere case of Poison Ivy. This stuff works EXCELLENT to kill of the posion. I was covered in it, from my face and eyes to my feet. Along side of clearing up the posion ivy, the side effects sucked. Felt very weak. Couldnt maintain an erection. I didnt have an appitiete and lost weight. After i was off the Prednisone, i broke out with acne on my face and back. I gained my appitite back but have been drinking alot more water. I feel like i have my strength back also.
