I Have A Hole In My Throat. I Think It's

I have a hole in my throat. I think it's on my tonsil. The other ones pussy and I had a flu for the past couple days that's cleared up. The puss on the left tonsil subsided but the right tonsil still has a hole the size of a pen cap. It looks pretty deep and I can't see where it goes. I'm worried too because I have been a long time chewer of the tobacco variety. Is this a dentist questions, doctor question, or oral surgeon question?
