I am a 26 year old female. About 10 days ago i was eating a hotdog and when i swallowed it, it burned my right tonsil area, which began to swell up. Then I noticed that a lump had also appeared under my tongue. Everytime I eat, the lump under my tongue swells up, and my right tonsil area burns and swells as well. It almost feels like the food is getting stuck. A few minutes after I eat... the swelling goes down a little, but the lump is still there, and there is this feeling that I have something stuck in my throat. I have been rinsing with Listerine and salt water for the entirety of this irritating problem. It has not helped. I am a smoker so, of course, the whole worry of oral cancer is on my mind. Is there anything else this can be? And should I go to an ENT or just to the ER? I'd really like to get rid of this thing.
