Weird combination of symptoms.. proctitis?

I got started on a pred taper and Humira not too long ago, after being in more or less a continuous non-stop flare for about 3 years now of left-sided colitis diagnosed by colonoscopy, with my old symptoms being diarrhea with blood 6-8 times a day.

I think the humira is working.. I have 2 or so "normal" BM's a day that are textbook of a healthy person's.
However, in between those, I'll have numerous episodes of extreme urgency (sometimes causing incontinence) and when I sit down on the toilet, it's mostly gas, blood and mucus followed by very uncomfortable cramping/spasming, and feeling like my rectum is extremely full..

Has anyone else had this mixture of normal stools but these awful flare symptoms in between? I'm planning to tell my doctor on Monday but I'd like some ideas of what to suggest this might be and what to do about it...

thanks and goodness bless anyone who has any sage advice

yes, you do not get to make too much of a couple of normal mb (except that formed stool is good) if they are inter-spaced with a number of bloody mucus bm. it does sound like the blood and mucus is lower in the colon, below where the next formed bm is positioned.

either give Humira more time, add another oral med, or try the rectal meds Quincy mentions.

good luck
