Hello, I have been having pain in the upper portion of my cheek, around the back towards my molars. I don t see any ulcers or anything alarming to the naked eye. The pain though, is persistent. Is it possible that my cheek rubs against my teeth in a way that is constant enough to cause pain, but not drastic enough to break the skin or cause issues that someone can see? I feel the slightest raised area with my tongue in this area, but cannot see that raised area under close inspection with a flashlight in my mouth.
