UC'er with possible fistula?

I've read where UC'ers can have Chrones symptoms. I get the mouth sores when flaring badly and GI says this is Chrones related, although the initial colonoscopy didn't show the granules nor did they do any other testing when the mouth sores surfaced.

Now I'm wondering if there is more to it?

I've been in remission of my UC for two solid months.  However, this past week, I've had soreness in my bottom and some extra bm's.  I thought it was something I ate that didn't agree (a nutty crunchy salty pretzel, chip mix thingie).

Anyway, I've had lots more gas the past few days and now I have a "sore spot" in between my anus and vagina.  It is also bleeding ever so lightly, when "tapped" with TP on the tip of my fingers. 

Is this a fistula?  An abcess?  Taking Canasa seems like the wrong thing in the wrong place.  It really hurts after going number one or number two.  Please help!  I have had this about a year ago and it was in the same area, only like a cyst.  I only had blood come out and it went away after awhile. 

I use Canasa suppositories when needed.  Whether it's UC or Crohn's, if you've got inflammation in the area, and it's helping, I say go for it.  I occasionally get so inflammed around my anus that I bleed slightly, without a fistula or anything else.  I think the skin just kind of gives up and I end up with very small tears.  I try not to let things get to that point, but a day of more frequent than normal bms can do it.  I try to use Calmoseptine (OTC, request from your pharmacist) when ever I start to see irritation.  That helps with the burning and itching, and protects the skin.  Usually a couple days of that brings things back under control, assuming that it was just a bad day or two and not an extended period of D.

The sitz bath was a good suggestion.  I find that they may sting at first, but once you get past the first few seconds, it feels really good.  I have skin tags, which makes it hard to wipe.  (Too many nooks and crannies!)  So it's one of the few times I feel really clean, too.

I would discuss the situation with your doctor.  At the very least, your current treatment isn't controlling all your inflammation.  And you have a legitimate reason to think that you may have been misdiagnosed.  (Which happens a lot with UC and Crohn's.)  If you can't get answers to your questions, get a second opinion.

Good luck.
