I'm so sorry to repeat a question -- but am extremely nervous. Exactly one week ago I had unprotected oral sex with a man of unknown status. I only performed oral sex for about 20 seconds; he did not ejaculate in my mouth. We then had vaginal intercourse with a condom. I do know that the man was very sexually active (with other women, not men).
For the past three days I've had extremely enlarged lymph nodes. I know this is very early to experience symptoms from exposure, but I can't help but notice how bad it is. I do not have a rash, fever, or body aches. I do have a runny nose -- I know this more often indicates a cold and not HIV exposure. I also have a slightly scratchy throat.
What is my risk of having an STD, and what could it be? I know my symptoms may just indicate a cold, but I can barely swallow it's so bad. Again, this is exactly seven days after exposure.
