First, re-read what Vance told you.
If you can't life with this go ahead and Test for
gonorrhea and NGU, testing at 3 to 7 days post exposure.
syphilis at 6 to 8 weeks post exposure.
Herpes at 4 months post exposure.
When should I go get tested?
See a Dr for your symptom it has no relation to a STD. Low risk for gonorrhea and NGU, lower risk for herpes and syphilis. At this time see no reason to test.
