When I feel the inside of my mouth with my tongue, on the inner side of the cheek, I feel a lump or like a small speed bump (like a raised line) in my inner cheek. It is about a inch long. Is this a blood vein or vessel or is this something else. I don't feel it all the time and when I pull my mouth open, I see it sort of.
If anyone has any idea's please let me know.
