Since herpes lives in the nervous system, why wouldn’t it cause itchy sensations in other parts of my body, besides down below?
When I looked online to see if there was any connection between herpes and general bodily itching, I did find several others who were concerned about the same thing. Though others reassured them that there was no correlation between herpes and random skin itching, I did find it interesting that there was some discussion about it already. I thought maybe some of you who frequent this site might have the same concerns and some i...
