Has anyone else had trouble with bone and Crohn's? I went in for a CT SCAN to see if I was going to have resection surgery. My terminal ileum is looking better so my GI is hopping the humira is working. BUT, I have avascular necrosis of femoral bone. I have been reading up on this and see its linked to steroids, Crohn's Disease, etc. Was wondering if anyone else has this issue, and was wondering what I had to look forward to.
