Question:

Answers:
It sounds like a canker. You wanted scientific so here it is. A canker sore is also called aphthous stomatitis which is a recurring condition characterized by the eruption of painful ulcers, commonly called, canker sores, on the mucous membranes of the mouth. The cause is unknown, but there is evidence to suggest that aphthous stomatitis is an immune reaction.
