yes, all of that is possible.
If you have bubbles under the skin of your fingers, then these definitely sound like blisters to me and you should be seen right away for a swab test of your fingers for whitlow. From you initial description it didn’t sound as though you had blisters but now it definitely does! Please – go and have them was tested, hopefully using the PCR vs. culture, as PCR is 3-4 times more sensitive than culture.
If this does turn out to be whitlow, you will not shed asymptomatically from that area – only when you have an outbreak because the skin is too thick to shed.
In response to your question about pain – not everyone has pain with herpes but most everyone that I have seen with herpes has some discomfort when the lesions are swabbed, even if the lesions, untouched, are not painful.
I doubt that in two weeks your hands and genital are going to be covered with blisters, but I so hope you will go see someone to evaluated your hands NOW due to the bubbles under the skin that you describe.
I’m not clear what you mean about your body’s antivirals forcing your body into blisters. It is actually a lack of an immune response that allows for initial blisters but as the immune system (is that what you mean by antivirals) gets into gear, the lesions tend to come less frequently. I guess I”m just a little confused by your question.
I am also concerned about what you describe as the skin lesions with red centers. Do they look like targets? If yes, it could be an immune response to herpes called erythema multiforme. You might want to look up pictures of that and see if yours look similar.
