My son is 20 years old and for years he has suffered with constant mouth ulcers
. His dental hygiene is top in his priorities and always has been. Lately over the last 6 months, maybe more they are getting more frequent. He must has them all the time now maybe a week reprieve. He has one now that is on the thing at the back of your throat that hangs down and its huge, he is always in pain, he could have 2,3, maybe more at one time. but this is first time on that part of the throat..
