Well Lilsxyhba, Sad to hear that you have to suffer because of the ulcers. These ulcers can be due to a viral infection or possibly due to stress
. It will be very difficult to comment upon what kind of ulcers they are as you havent provided enough information and also I have not seen the ulcers clincially. But nothing to worry about. you can use any anaesthetic mouth was (a mouth wash which has a local aneasthetic) this will help you to tackle with the pain.
If they are stress ulcers they will take 7-14 days time to go. Just keep your mouth clean. use a antiseptic mouth wash twice daily like chlorhexidine
