The mouth ulcers run with Crohn's and colitis dx... And can still happen after a pouch.

The head things? No idea if they're linked.

I never had them before my colon was removed for UC and don't have them now with my cuffitis. That said I think you should have it all checked out, especially since they are appearing with flares.

I have been getting painful pimples on my scalp too off an on since my surgery. But mine do not seem to be regular pimples as they are hard and red and if I try to scratch them, they just hurt and they leave a open area. They are not regular pimples. I get these on my back sometimes too. I have no idea what they are other than it is crazy how weird my body gets sometimes.
