Hi,
I get ulcers ALL the time! I find mine are flared up if i eat anything too acidic, such as tomatoes/fruit etc. It's my own fault for pushing my luck as my mouth lining is still so sensitive!
And as others have said, my mouth also flares up with thrush persistantly. But i've found drinking a probiotic drink every day keeps it at bay for me!
Hope it feels better soon.
All the best,
Michelle
