I was having mouth issues about a year ago that were intermitent and resolved themselves. I woke this morning with what felt like a cancor sore pain and when I looked in my mouth, I noticed that if I pulled my tongue over there was what looked like a tag of skin or something. I had felt it with my tongue but never noticed it before. It is next to what I think is my lingual muscle under my tongue, right near the base of my tongue.

Any ideas? Are there things such as flaps of skin in the mouth?
