3 weeks ago I had unprotected vaginal intercourse. 3 days after the incident I had a full battery of tests for std's, Herpes, and HIV (blood work & CBC). All came back negative.

What were my risks (odds of contracting HIV)?
Were/are the tests worthless and should I be re-tested?

Now at 3 weeks later I have had many sleepless nights. Several of those nights involving alcohol and waking with hangover. Am now dealing with post nasal drip, waking with headache/sore neck, scratchy throat. Also when I have been trying to get back to training on the bicycle I feel awful, w/elevated Heart Rate and poor recovery. I had surgery in August and have been on prednisone since. Now trying to taper off. Also had been taking avelox and stopped due to "itchy feeling" since my episode three weeks ago.

Now dealing with an "itch" in various areas of my body with no visible rash. Is this of concern? Also on occasion have the same feeliing in genitals, is this to be of concern?

Mentally not doing well with this as starting to feel like a hypochondriac.
Need answers, help and direction.

Help put my mind at ease
