So the HSV 1&2 IgG tells you that you have type 1 OR type 2 OR both.
You need to get a type specific IgG test. If they are able to give you the test you had, you should be able to get a type specific test.
Globally, 67% of people under 50 have oral hsv1 - think cold sores or fever blisters on the mouth - and 90% never get symptoms. Your test may simply mean that you have that, and not genital herpes type 2.
Your risk for hsv2 is very, very low. Your exposure time - if this is your only encounter - is very brief. Your genital symptoms cleared up with the Clotrimazole, suggesting that it was indeed fungal.
I don't know why you are getting lower abdominal and testicular pain, but have you seen a doctor for that? Maybe you have a hernia.
I know you are very scared, but even if your partner had an STD, your exposure was very brief. I don't see a lot to worry about here. See if you can get a type specific test, and we can figure it out then.
Have you tested for other STDs, like gonorrhea and chlamydia?
