Well, I think the sore could be other things of course, and the testing will help you be clearer about what might be going on. Let's see how the antibody test comes back and the swab test. If the swab test is positive for herpes, lets say HSV 2, and the antibody test is negative for HSV 2, that tells you that you likely have new infection (virus is present on your skin but not enough time has gone by for you to have made antibody yet). If the antibody test is positive also, then it suggests that you have an established infection, but one that you may not have known you had.
Frankly, I think the chances of you getting herpes through using a razor are very very small indeed. If you do have herpes, I'm guessing you already had it. What is your sexual history like? By that, I mean about how many lifetime partners have you had and when did you last have sex? Anyone new in the last couples of months? These are all things to think about as you try to sort out what might be going on. Please feel free to get back to me if the results are confusing for you.
