As shown in the picture, its seems like I have a lump/ulcer or something on my left tonsil. Don't really experience any pain, occasional it feels like theres a lump back there somewhere, it comes and goes really really fast, like gone in a couple of seconds, and I do experience this sensation on both sides. For the past 6 months or so, I have been getting tonsil stones on each side, they started appearing on both tonsils at the same time. Should I go to an ENT and have them look at this or just my GP?
