Hi, I was diagnosed with Crohn's in Sept. 2012. I had a fistula and a micro-perf of my pouch. After 19 days in the hospital, my doctors decided to start Remicade. NONE of the testing-biopsies, blood work... showed Crohns. So, I've been on it since and have started to experience pain in my lower back that comes and goes, and in my ankles. My last 4 blood checks were totally normal, with SED rate as low as 14 (the most recent, it was 33). I'm on 9 week cycle, and my GI doc has ordered go back to the single dose.(the doubling the dose is a long story). I was under the impression that once you increase the dosage, you can't go back. Of course, did I ask him yesterday when I was there-no. Can anyone help me with this issue? Thanks!
