Hello! well, about three weeks ago i started getting a cold.. had a sore throat for about two days.. I noticed one tonsil on the right side was swollen but it did not hurt because my sore throat had went away.. well now it is a few weeks later and it is still swollen with no pain. I have post nasal drip and allergies so I was wondering if that would be the cause or if it would be something else. I went to the health center at my college where they said it was probably allergies but since it was not my real doctor i still worry. any suggestions for a swollen tonsil but no sore throat?
