I hope the Entyvio helps you! It is a monoclonal antibody and targets inflammation areas. I was surprised that my collagenous collitis had disappeared because I thought I had it for keeps. Crohn's Disease is elusive at times. Symptoms can come and go. I also had a duodenal stricture which I understood was permanent. That is no longer there either. I know these weren't misdiagnosed because the doc did an endoscopy (EGD) and actually stretched the stricture during several endoscopies. The colon was biopsied. I'm glad I finallywent to Mayo Clinic, which was where I was diagnosed with Crohn's. The doctors before Mayo told me that I would have to have the duodenum and part of my stomach removed because of the stricture! That sent me running to Mayo! I still have my stomach, intestines, getting Entyvio, and am doing very well! (4 years now.)
I wish you the best with your treatment!
