I have had deep extreme itching all over mostly over my entire upper torso and arms for 17 years, From 2 days after i had unprotected sex with a promiscuous female stranger, who said she had some type of fatigue virus before we did it, but i decided not to worry about getting it, and got it, so it is probably a virus.
