Hello, I have a hard small lump just below my left tonsil, at the top of the jawline. It does not move and it has been the same size for a year (when I first noticed it). It's not tonsiliths which I removed from that tolsinl area regularly (right side tonsil does not produce tonsiliths). It is not painful but feels as if I have something stuck in my throat in tha area. No pus, No redness, jyst a hard mass below the skin. Could this be an ingrown tooth?
