ve also heard that sometimes HPV has no
symptoms, and that
hives are sometimes caused by viruses. My worry is that I may have something that has no symptoms, but that my body is reacting to and releasing histamine, which produces these hives. Am I being stupid? Am I even at risk for anything other than Herpes, Syphilis, Gonnareha, Chlamydia, or HIV having only had oral sex? These are the things I was tested for. Any insight would be greatly appreciated.
