I have had this reccuring sore throat going on past 2 months now and I am confused as to what it can be. I'm a 24 year old male and this has never happened to me before. I've had pretty good health pretty much all my life. About a month ago I went to the doc and he looked at my throat and just gave me a seven day course of antibiotics, it helped but it just seems to be coming back and not going away. I've also had stuffed nose for a few days now, but that usually happens around the spring time. I know this is not an std forum but I was wondering if the sexual exposre I had 3 months ago could have anything to do with it, (unprotected vaginal sex for 2 minutes) I have already tested negative for Hiv 3 times out to 9 weeks and have taken some other std test which are negative. The throat got worse when I would smoke a cigarette, so for about 2 weeks now I havent smoked. What do you think I should do? What test can I take for my thraot to see whats wrong with it? What are some of the causes of a sore throat lingering for a few months? sorry to make it so long but I am just confused as to what it can be, hopefully you can help me out, I know nobody can make a firm diagnosis over the internet but any information would be great. Thank you so much in advance.
