I have had sore pain in throat for a couple of months, together with some swallowing soreness and discomfort. I had a gentle peek behind my tonsil a few evenings ago with a Q Tip and saw a butterbean like lump, slightly yellow and quite prominent. This is just inside the arch of the tonsil, on the wall of the throat, opposite the inside edge of the tonsil as it were. I have an appointment to see an ENT, am worried that this could be some sort of tumour.
