Hello, I am 23 years old and about 4 months ago i received oral sex from a woman who someone told me later to be a hooker. For the past few days I have had Diarrhea. I woke up with a skin rash two days ago that lasted about fifteen minutes that kinda resembled Hives( reddish area, small white bumps). Might be from my sisters cat.. and for the past two days have had a semi sore throat and yesterday had awful muscle aches, shivers, and a mild fever up until i took medicine and it helped most of it today. I know people say you dont get HIV from oral sex, but i dont know and if anyone could help me out it would really be appreciated.
