Hello doctor, i have had unprotected sex in the last few years and the last time i went for an HIV test was 3 months ago and the results came out negative. However, i have rashes in my groin area which itches a lot with blisters on the head of my penis and sores on the penis itself and they itch. I am also suffering from joint pains. Also i feel pricking pains in my muscle My body itches especially my arms and when i scratch, my skin turns white. My tongue is also becoming white and i have burning sensations in my buttocks down to my legs and. Am very much worried as i feel i have been exposed to HIV/AIDS and wondering if late HIV infection is difficult to be detected by anytibody test. Chlamydia and VDRL tests all came out negative. Please help me.....
