Hello! I am 19 years old and I have noticed for about 4 months that I have a swelled tonsil, only one. I didn't did anything about it at first because when it hurt I waited a while for it to disappear but it actually never went away. When the tonsil stop bothering (didn't hurt anymore) I stopped paying attention but the swelling never went away. Lately I have paid more attention to the fact that it is already 4 or 5 months that I have that same tonsil swelled and painless and I am beginning to worry. Is this something that I should be very worried about?
