Suggest Treatment For Irritation In Tonsil

Hi I have noticed over the course of the last two weeks that I have the sensation of something below my tonsil. It doesn't hurt or anything, and it mainly goes away when I gargle salt water and eat food. I haven't had any trouble eating or anything like that and haven't been feeling sick. Just that feeling of something under my right tonsil or it could be the tonsil itself. I used to smoke (only for a year and a half) and I have quit permanently. I also drink on occasion.
