Circumvalate papillae are normal. Everyone has them. The problem is that since they are not usually seen, patients are not used to their appearance. And when they are spotted, they look weird and scary.
They do not contain lymphoid tissue, unlike tonsils, so their enlargement is nothing to do with any infection. Even iff circumavalate papillae are enlarged, they do not need a biopsy or any other treatment or medications.
Your tongue IS normal right now !
The tonsils though are another matter. They contain lymphoid tissue and their enlargement can be directly due to an infection. If they are enlarged and they dont subside, AND if they are painful, they may need surgery (Tonsillectomy).
