Hello sir, my sex exposure was 11 months before with prostrate having condom. After this incident I was experiencing shore throat, muscle+joint pain, 1 months fever, tongue yeast infection, extreme headache. During this time I have tested elisa ab/ag for ten times (1.5,3,4,5,6,7,8,9,10,11 months serially). All are negative. But still now I have some of those symptoms. I must inform you that before this incident I was completely ok. So my question is. Whats is going with me. Is hiv exist my blood but can't show up. Should I continue to test again?
