two weeks ago i had causal oral sex with a man it only lasted a few seconds but 4 days latter i developed a fever and headache, the day latter i developed a sore throat and had pain swallowing, this was controlled by paracetamol and ibuprofen. after 4 days it wasnt getting better and i had developed exudates on my tonsil, i also had developed a rash on my tongue red blood spots down the side of my tongue that fits with step throat, i was given pen v by the doctor and with 36 hours i was better. Now 4 days post that i have developed a single small ulcer in my mouth under my tongue. I have also noticed some yellow lumps at the end of my tongue however these aren't ulcers and i believe them to be lymphoid aggregates. I had no pain during my illness in either location, no ulcers during my illness and regularly suffer from canker sores. I believe with the response to the antibiotics and the strawberry tongue blotches the chance is i had strep throat, though would be quite coincidental with the oral sex, however this one ulcer worries me though it looks like my standard canker, could i please get ur opinion, i live in teh uk so routine hsv 1 and 2 screening isnt done, and i also understand if u screened the population anyway approx 80 + % would have hsv1 and the number of people with hsv 2 isn't know but thought to be between 20 -40 %.
