HIV is inactivated in saliva, HIV is inactivated in air. Those are 2 reasons you and everyone else in 40 year HIV history can't have HIV from oral sex despite cuts, chapped lips etc. So you wasted your time testing.
Symptoms aren't used to diagnose HIV and you have no medical training, so it is not surprising that you are puzzled trying to self-diagnose what a test has proven you don't have.
Everyone gets flu but few have HIV. Living with fear based on the faulty premise that you are dying there is a high probability that the self diagnosed symptoms are psychosomatic and you have nothing wrong anyway.
Consider therapy for your HIV obsession, as it is quicker than waiting around for tests, so might provide quick relief.
Cuts and chaped lips during oral sex is a risk activity?
I did overkill and meant no risk despite any mouth abrasions which I thought was pretty clear message - so just stick to this simpler reworded message instead. No one in 40 year HIV history got HIV from oral sex.
