all of that info is irrelevant.
if you had unprotected sex and tested 3 months post your LAST exposure...then you have a conclusive test result...proving that you do not have hiv.
Your post is a little hard to follow. First of all....your cancer and shoulder pain/nerve damage is in no way related to HIV.
HIV tests are reliable at 3 months post an exposure (an "exposure" would be unprotected vaginal or anal sex, sharing IV drug works, or via mother to infant).You can believe the results...you do not have HIV.
I can take up to six months for you to seroconvert after exposure. That means, if you have engaged in any risky behavior since your last HIV test then you should be tested again. Your symptoms do not sound like HIV. HPV does increase your risk of catching HIV, especially through anal sex if the warts are present. However, I would get to the doctor and have him check for a recurrence of cancer. I'd do it today.
Move along..3 months is conclusive and has been since 2004.
