My doctor always loves chemical cocktails of a few drugs so I never know what is sending my body off into left field when they start to act up — lets put it this way, I’m 38 and started to get pimples again!. I wish I had a little better audience on my blog when it came to the Crohn’s communtiy to get a better response to your inquiry. The only wisdom I can lend is what I keep reminding myself — I could be back in the hospital, need a hip replacement as a result of my prednesone use or have had to endure surgery. So I suppose a few pimples is the worst of my concerns. Good luck finding the answer if it does not come out here — and feel free to check back from time to time.
