question: I have a sore on the inside of my cheek. I do have oral herpes but ive never had a cold sore on my inner cheek. it hurts like one, but im not sure if it is a cold sore or a canker sore? also, it is directly in a spot where my teeth come together so i am wondering if i may have bit myself, but it hurts quite badly and has been there for a few days now. help!
