Hello @marion49 and welcome to the Digestive Health support group on Mayo Connect. I'm sorry to hear of the difficult decision you are facing regarding the recent diagnosis of Crohns Disease. I found a discussion group on Connect that might be helpful to you. Here is the link,
--Diagnosed with Crohns at an older age
https://connect.mayoclinic.org/discussion/diagnosed-with-crohns-at-age-61-from-routine-colonoscopy/?commentsorder=newest#chv4-comment-stream-header
In this discussion you will meet @catherine1290 and @lucismith. Please feel free to post to either of these members directly and ask questions about their treatment decisions and health issues.

What is the most troublesome symptom you are dealing with right now? How long will it be until you can get a second opinion from a different doctor?
