Mouth, throat, ulcers are totally Crohn's related-- keep in mind it's from oral to anal...
My solution, having just had a few: Vitamin E capsules. Get the Vite E derived from various sources, Natural Factors makes a cheep one.
I chew the caps, spitting out the gelatin once the vite E is in my mouth. 1 cap 3x's / day until it clears, took me 3 days and then I kept it up for another 2 days to be sure.
Vite E is great for healing the mouth, including swollen gums.
I also used it when an ulcer showed up on the skin bordering my fistula. Worked like a charm.
