Hello,
In late 2009 I had unprotected intercourse with a woman. 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. I took the meds and didn't think much of it until recently. It seems as if this is consistent with oral HSV infection. I've never had a cold sore before, or noticed any blisters on my genitals, though at the time I was feeling so sick I don't recall examining my genitals nor any pain or discomfort in that region. On the other hand, bacterial tonsillitis isn't supposed to cause oral ulcers, and the antibiotics seemed to help recover. Now I'm a bit confused and anxious.
