I recently had anal sex in which the condom broke and I did not discover this until after the fact. About 2 weeks after this happened, I came down with what seemed to be a very nasty cold that started with the usual tickle in my throat. My symptoms were a runny nose, persistent cough with a phlegmy feeling in my throat, bad headache, a fever of about 100 for a day or so, and swollen and slightly sore lymph nodes in my neck. No sore throat, no major muscle aches, basically nothing so bad that I was stuck in bed because I was so sick. Although I have no evidence that the person I had sex with has HIV, I am still pretty worried that my symptoms might indicate ARS. Do these symptoms sound like ARS? How severe is ARS usually?
