Yes, get a second opinion. When I went to the emergency room that doctor had never seen anything like it after looking at the numerous CT scans they did on me. He was calling around to other doctors to see what he should do. He didn't feel comfortable doing the surgery so they sent me home a couple of days later and I had to schedule the surgery. First they sent me to a doctor who only deals with stomach issues. He is the one who performed the surgery. Only thing is, I was in a lot of pain for the first week. It is staring to feel better now.

I was diagnosed with it about a year ago. My protocol was 2 meds for constipation, 1 med for inflammation, that's it. I found a great nutritionist, who taught me how and what to eat.
Doing quite well. Yes, find another Doctor.
