question: I have pain when I swallow, and unfortunately I seem to be generating a lot of saliva causing me to swallow.  It is painful, as aforementioned, and my tonsils are in pain consistently; never-ending. I recently had a root canal and I took some Hydrocodone and I'm not sure if its a side effect to the drug.  I am also experiencing runny nose from time to time, seemingly when the temperature drops or i take some clothes off.  My main concern is my pain when swallowing and my tonsil pain.  I'm a healthy 21 year old, or at least I was save for a few weeks ago.
