I'm a 19 year old male and I'm super worried I may have contracted something :/
2 1/2 weeks ago I gave oral sex to a women for a few minutes, which was followed by a brief vaginal insertion. (only 1-2 minutes). Only 2-3 later, I started feeling off: cold-chills, runny nose... 2 days later (5 days after the stint) my tongue began to feel burnt (rough), accompanied with a seriously bad sore throat, nasal congestion, and the urge to sneeze. I also noticed very small red dots on the backs of my hands (vesicles?), and pain under my ears and on the backs of my hands. Moving forward up until now, I developed severe congestion that drains down my throat, irritating it further. I still have cold-chills and feel very sickly (achy and feel crappy). I also noticed my eyes feeling itchy.
I visited a doctor 2 weeks ago when my throat started hurting, they ran a strep test: negative
I visited my family doctor 2 days ago, and he said it was obvious that I was fighting something. He said it could either be a garden variety virus or more likely, a bacterial infection. He prescribed Cefnidir 300mg twice a day, for 10 days. He seemed certain it was an infection in my throat or surrounding it, especially after looking at my throat (very red) and when I mentioned the small dots.
So far I have been taking it as scheduled, currently on my 4th dose of it (day 2) and nothing has changed. The only thing I notice is fatigue after taking it. (sign that it's working?)
Can anyone confirm these symptoms as being part of a common virus or bacterial infection? My biggest fear is HIV, I don't think I could handle that diagnosis. I'd even be relieved to hear if this is symptomatic of a less serious or even curable STD.
