A couple weeks later, I was very sick with what was diagnosed as bacterial
tonsillitis. Was prescribed amoxicillan and I recovered quickly. Tonsils were swollen to the point that I could barely speak, fever, white exudate, but before that I noticed that part of my right cheek felt sore and enlarged. As I got sicker, that receded while an oral ulcer developed on my left gum on the inside that seemed fairly large. At the time, I showed the clinic doctor but he said it looked like a canker sore.
