It might sound simple but I've always found that gargling with mouth wash several times a day helps heal the ulcers much faster. And it usually numbs everything for a bit.
Hope you find relief soon. Good luck.
Oooo! you poor thing. I remember having a mouth full right before I was diagnosed. I was in tears. I ended up calling my dentist. He was much quicker than the family Dr. I can't remember what it was and fortunately i have never had them that bad since. hope I don't speak too soon. Good luck.
