Approximately six weeks ago, I had an encounter with a stripper/sex worker in Japan who let me finger her; that finger, with some vaginal fluid, eventually ended up in my mouth and on my toungue. No other fluid contact took place that I am aware of.
At about 23 or 24 days after that, my salivary gland on my left side in the cheek got rather swollen internally, but over the course of 2 or 3 more days went down, but definitely appears swollen in comparrison to the right side. Since I really never looked at my mouth so intently prior to now, I can't tell if the right side is swollen or not. I also experienced swelling below my toungue.
At 28 days I had a PCR DNA and it tested negative.
At 35 days, I had an RPR and it was negative for Syphilis.
At 37 days, I saw my doctor and he precribed 500mg of penicillin at 4 x day for the swollen salivary gland. He thought my fear of syphilis was absurd, and I didn't really raise HIV at the time. He admitted that he had no real experience with swollen salivary glands.
At 40 days, I took an ELISA for HIV, and it tested negative, as well as another RPR, which also tested negative.
I am here at 43 days and there has been no discernable change in the status of the swollen salivary gland, but the swelling below the toungue seems better.
So, my questions are:
1. Should I consider the RPR and ELISA at 40 days conclusive in ruling out an STD here, given the activity in question?
2. Though this encounter probably rates at low risk, should I be worried about HIV and can I draw any comfort from the negative results thus far?
3. If it is not HIV or Syphilis, why aren't the antibiotics being helpful?
4. What can I do at this point to rule out an STD?
5. Is this just one of those weird co-incidences?
