I am new to the group. I was diagnosed with ulcerative proctitis 6 years ago. After being on lialda and Imuran for 6 years, these drugs are now failing me. I am moving on to biologics. My first infusion in 6/7. In addition to sitting for 2-3 hours, what can be expected in terms of side effects, being able to work and exercise the day of/next day etc.?
