Colitis moving along colon

Was just wondering if anyone else notices that the UC moves throughout a flare-up?

In my case, when the flare began to get going I had urgency in the rectum but nowhere else and now about 4 weeks later that has gone but I now get an ache / urgency feeling in the descending colon and the transverse colon. It seems a bit weird because I imagine UC to be ulcerated skin which I wouldn't expect to spread or move elsewhere?

What are you doing for treatments?

That's what happens to me when I don't get it under control. A few years ago I had a pancolitis but thankfully treated it with Azathioprine and pred. Now it started left sided again but it's going all the way to the flexure into the transverse colon. I hope I can stop it from spreading more because pancolitis is no fun.

Do you have Pancolitis?

I will give you an example my dentist gave me once about a tooth ache - when the initial pain sets in, we feel the pain, we react to the pain but eventually the body becomes accustomed to the pain and "minimalizes" it so we can function. I feel that is the same thing we feel with our colons. We start with the initial pain, we get used to it, but as the inflammation progresses, we get a new type of pain or discomfort and/or symptoms and the cycle repeats. So unless the "ulcerations" or inflammation stays in one area, each area or spot can feel different then the last, if that makes sense?

For instance, when I flare rectally I get pain upon going, some urgency, no cramping or pain higher up. But when it goes further to the sigmoid, I get lower abdominal cramping along with the pain and urgency, not so much rectal anymore, to my Tranverse, extreme cramping, extreme urgency and severe pain, not so much sigmoid pain or rectal pain.

Yes ulcerative colitis is known to start in the rectum and then spreading up to the descending, transverse and ascending colon. Unlike Crohns where the inflammation can show up anywhere with no pattern.
