About three to four weeks ago I had protected sex with a sex worker. Just a couple days ago out of nowhere I started it itching. It hasn't been a very bad itch but an itch none the less it also isn't constant and actually is more in my inner thighs,legs, face, and arms more than my pubic genital region. In fact I don't itch there much at all. There are tiny red bumps scattered on my legs and some bigger ones that look like pimples or mosquito bites scattered also but they are very secluded no bump is less than two inches away from eachother and that's only one spot that even has two. I haven't found eggs or actual lice just itching and some redness. Could it be from stress or something worse what should I do?!!!
