My 51 year old boyfriend told me the roof of his mouth was sore . . . I asked to look and saw on the left side 3 small what look like holes in a row equal distance apart running front to back along where the hard and soft palet meet. Also further back more to the middle are 2 what look like small sores. Ones a bit bigger and seems to have infection in it. I think the 3 holes are something different than the other 2 towards the back. He says they feel like sore spots when he runs his tongue along it. What could they be?
