September 2010 I had a very strong infection in my throat together with very high fever and swollen tonsils for about a month. After having taken antibiotics everything was normal again and since then I have been in excellent health. Last week, around wednesday, I started feeling a little bit sick and some tingling in my throat. I had rest for a couple of days and everything was seeming okay until I began feeling pressure in my left ear, but no fever, no swollen tonsils, nothing. I looked in the mirror and found an ulcer on the soft palate near the uvula, it is small, white/grey and surrounded by a red hallow. Is it the cause of my ear ache? Another detail I noticed: my right tonsil is visible while the one on the ulcer's side is flat, I can't see it, as if I have none.
I remember that last September they were asymmetric as well, could it be because of that old infection?
