Endo after hysterectomy

Has anyone had returning endo after there hysterectomy. I was doing okay for a while and now I'm having the same kind of pain that I had prior to my hysterectomy. I do have an appointment with a doctor tomorrow about it, but I also found out that something called carboxymethycellulose which is in over the counter laxatives such as metamucil/citracil can cause terrible abdominal pain which I have been having a while. This product is also in some gluten free products (I'm gluten intolerant) . Has anyone else have these type of symptoms? I'm so tired of being in pain and thought the hysterectomy would help but I feel like I'm back to square one.
Thank You to anyone who can help with advice.

Hopefully someone will be able to give you an answer.
