My mom thinks my tonsils are growing back and i've been having some throat problems?

Question

I had them taken out when I was 2 and the other day she noticed that one is growing back

Answer 1

I agree.  They can grow back - at least partially.  You might have to visit the doctor again.

Answer 2

Before loads of people say "don't be stupid, they can't grow back" I can categorically say that one of mine has indeed grown back since it got removed.

That's all I know. I can't be any further help.
