There is no blood test for warts, and there is no HPV test for men at all.
Did you point this out to your doctor? If not, why not? Your doctor can't read your mind.
It might be a cyst, and that would be more likely than a wart, as warts are on top of the skin, not under it.
In any case, you need to be seen for it. Most of the time, cysts aren't anything serious, but they can be indicative of other things.
Aj
maybe its a zist or however you spell it.
