Go to the doctor and get the bump checked in person. Don't pop it, don't do anything to it, just let the doctor see it. Get it checked as soon as you can - go to an urgent care if you can. If they think it looks like herpes, INSIST that they do a culture or PCR swab on it, and make sure they type it to find out if it's hsv1 or hsv2.
Getting it cultured or swabbed is the best way to find out what it is. Even if you do another herpes blood test, it doesn't tell you if what you have now is herpes or caused by something else, like a clogged oil gland or something.
What kind of exposure did you have? Oral? Vaginal? Anal?
To save you some money -
You never needed to test for all 3 heps. Depending on your age and location, you've probably been vaccinated for hep B. Hep A is transmitted by fecal matter (poop) and is usually transmitted by contaminated food or water. It can be transmitted by sex, but that's rare, and when it is, it's almost always anal sex.
Hep C is transmitted only by blood, and like hep A, it's rarely transmitted sexually, and when it is, it's by anal sex.
If all you had was oral sex, then skip the hsv2 test. You'd only be at risk for genital hsv1 from receiving oral.
Your gonorrhea, chlamydia, and trich tests were all conclusive. Your syphilis test should be redone at 6 weeks.

So go to the doctor today, and let us know what happens. Insist on a type specific culture or PCR swab if they think it's herpes.
