Personally I'd say no to the flare question..
My abdominal/GI symptoms at present are significantly unremarkable.
I've had a couple of bouts of SERIOUS, slow to resolve, iritis (always after a big D episode)
The first episode was associated with a R ankle full blown arthritis, and moderate urethritis.
A follow up colonoscopy a few months ago was visually and histologically normal..
BUT, I have continuing SI joint nocturnal pain, keep a close watch on costochondritis, and a few months ago developed anterior pretibial soreness/inflamed skin reaction (??erythema nodosum - probably..)
So for me, the EIMs far outweigh the GI aspects of the disease, and I am perpetually vigilant for new "odd" symptoms that may declare a new inflammatory diagnosis, even tho the bowel is "quiet"
