I had a sexual hiv exposure on 27 july with a paid sex worker because my condom was broke. I am facing some symptoms like skin rashes, pimples all over body, my legs, arms, overall body has become thin but I was 76 kgs first and now I am 78 kgs although I have become thin my weight has increased. Is it a sign of hiv? I have tested for hiv dna pcr after 17 days of exposure it was negative. Hiv elisa after 28 days was negative.
