Could horible pain in knees and hips while on prednisone or imuran be fibromyalgia?

Thanks for the reply. It's nice to know someone else has had the same symptoms. I did stop taking the prednisone and switched to imuran which I'm currently on and my legs got a little better not much though im still unable to work. I did stop the imuran once and my legs felt great but my proctitis flared and my back hurt really bad. It's almost like an arthralgia that moves around the body. When I'm on imuran my back feels better and the proctitis is controlled but my legs hurt. When I stop the imuran my proctitis flares and my back is in a lot of pain. It just gets transferred around. On the two biologics I've tried humira and remicade I get insomnia, anxiety, and panic attacks. On humira it was real bad. On remicade I only did one infusion and it lasted about a week but I got scared and cancelled the next infusion because I had the same feelings on humira and didn't wanna go through that again cause it was horrific. Yeah, I have a rhumatologist and he said he's never had anyone say they had anxiety and insomnia from biologics so... what do u do.

I know you're right I've been trying to make the decision to try remicade again for the past 5 days. I've been waking up in the middle of night stressing about it but so far that's the only thing that has taken away the pain from every part of my body and I need to do something. The only thing is I didn't just get anxiety I also got the deepest depression, and insomnia. Just from that one infusion although it did only last about a week and then went away, after that I felt ok. I'm just terrified that it could intensify the more I do it. That's pretty much what happened when i was on humira. As for the imuran and muscle pain prednisone caused the same pain in the same places knees and hips so I wouldn't say it's the imuran but my immune system doing weird stuff. I am curious to see if your leg pain goes away from stopping the imuran though, definitely let me know. Thanks!
