Kinda sounds like you might have Fibromyalgia along with your Crohns or it could be the reactive arthritis we sometimes get. I would not stop the Imuran. If you go onto the Fibro forum here you will probably find more responses on the Lyrica. If I were you I would get a referral to a Rheumatologist. With so many of us suffering with joint issues I personally think we should all have one on board. Good luck!
