Hi Christy.
I was also diagnosed in Sept 2011. I have the polymyositits and full lung involvement.
The imuran could be the problem. You would not be sure though unless you stopped it. According to my doctor, it can take up to 8-9 months to build up in your system enough to be effective. Are you taking anything else?"
I am also on prednisone. I am coming off the imuran, as it does not seem to be helping much, but does seem to be causing some liver issues. I am about to switch over to cellcept.
Do you have the myositis? If so, I have had wonderful results with IVIG treatment. It is expensive, but has worked wonders. brought both my lungs and muscles back.
Even though I am up to 70% lung capacity again, I still have the problem that you do at times. I also get exhausted very very easily.
If I were you, I would talk to your doctor about the nausea and loose bowels, and maybe think about trying a different med.
Until then, I hope things get better. It is hard enough dealing with this disease, without the added crap from the meds......
Keep up the good fight, and God Bless.
