I have these redish/ pink bump by the back of my tongue they don't hurt or anything can you tell me what this is?

Normal?: Circumvallate papillae are dome-shaped structures on the human tongue that vary in number from eight to twelve. If there is only one, is something else. See oral surgeon for exam.

Circumvalate Papilla: These bumps are always present in the back of the tongue, look slightly red and form a V-shape that points backward. If concerned see your dentist.
