My tonsils are sensitive right now. I was wondering if tonsillitis causes swelling of the guns as well. The pain in my tonsils is only on the right side, as well as the swelling of my gums (right side, all the way to the back). I'm very confused about what might be wrong with me. It's very painful to sneeze, swallow, open my mouth, smile, etc. not sure if my problem is a gum infection or actual tonsillitis. Please help
