Many people with CD in the small bowel have GERD. My GI explained it to me as a type of backwash problem. I suffered from severe heartburn and stomach pains at the time of the flare that got me diagnosed. I got scoped from both ends. I had lots of inflammation in my stomach plus the problems in the TI. While your problems could be related to the cimzia, it is also possible that you have some disease activity, CD related or not.
