I have Crohn's, Divirticulitis, and Uclerative Collitis. I had to be hospitalized for a bad case of Diviticulitis in October. A few days ago I started getting pain again. I went to the ER and they said is a combination of my Crohn's and Divirticulitis. They let me come home and told me to follow up with my doctor for a colonoscopy to be checked for a blockage. My doctor can't do it until December 11th. I am on a liquid diet. Today I feel like I have severe gas and need to go to the bathroom but can't have a bowel movement and can't pass any gas. I called the doctor on call but they didn't call me back. How will I know when I should go back to the ER or if it can wait until Monday when I can call my regular doctor.
