Azathrioprine Week 2

I have just finished my second week of Azathrioprine and finally feel that it might be working. Despite my set back on Sunday where I was very sick I've had a good week. I've noticed that I have much more energy and I haven't had much Crohns related pain. The only problem is the rash that has developed under my arm and on my back and chest. I know it can be a side effect of the medicine and the pros of taking it out weigh the cons but it is very sore and painful at the moment! I also went for my weekly blood test on Friday. I had to wait for an hour in pathology and have ended up with a big bruise and scratch!
