Flare not ending! Any suggestions?

I would try the biologicals, I waited too long to try them and ended up with having everything removed my colon and rectum that was me everyone is different. I was on hurmia and had no side effects but I did wait too long, by then my whole colon was affected in just 5 months. Stress did the damage.
I tried years ago a diet called elimination diet so no sugars, no wheat basically only lean meats and fruit and vegetables minus the ones with seeds. It did work once and put me into remission. Regarding cabbage, I could never tolerate it while in a flare-up. And controlling the anxiety is "so important.

Good luck you can do this..

First, I would ask about taking 4.8-grams of mesalamine oral per day, and one nightly 4.0-gram mesalamine enema. That's the maximum dosing for mesalamine, and is often tried before stronger medications like injectable-biologics.

You can try cabbage juice but I highly doubt it will do anything.

I have been on the biologic remicade since 2012, and I have not experienced any side effects. Side effects are rare but serious when they do occur.

You can ask about steroid enemas and rectal-foams which have less side effects than prednisone.

I had done all my tests. My stool routine showed 30-35 hpf pus cells and 8-10 hpf RBC . My stool culture showed only escherichia coli grown. My fecal calprotectin was 109 ug. These reports are of 2 days ago test.
My GI said that I am taking too mch stress for the disease . Should I do only hydrocortisone enemas or mesalamine also?
