Hi, I don t know how to explain this so well. There is a sharp or aching pain that will get worse and lessen and do that back and forth, and I can feel the pain when I swallow . When I put my finger back there, it s almost at like the back of my jaw, I m not sure if something is swollen. It s only on the left side and I don t remember for sure when it started, but I know it was yesterday or the day before.
