Welcome back. If you'll re-read my closing comments in your previous thread, I expected you would be back. Unfortunately, I don't see how I can help. Everything you ask now was answered then -- or at least you could predict the ansswers from my responses last time. My replies now are brief; for more detail, I suggest you go back and carefully re-read your previous thread.
A basic principle, which I see I didn't explicitly say last time but still was clear and understandable: The HIV tests you had are, individually and certainly collectively, among the most accurate diagnostic tests ever developed, for any medical condition. The results overrule all else: no matter how high the risk of HIV at the time of exposure and no matter how typical the symptoms may seem to be, the test results tell the truth. There has never been a single case of HIV reported in which someone was infected despite the test results you report. None. You aren't going to be the first.
"bad chest, cough, sore throat. This went on for 7-10 days, but sore throat lingered for 6 weeks. After this noticed thick white coating on tongue, some pain and bleeding when brushed. Oral thrush. This still lingers to this day....." and "...whitening of nails, muscle aches and pains, especially lower back, spasms, fungal foot infection, pain under one foot, waking up in night with numb hands or feet, and small white circular patches on my calfs...." Despite what you think you have learned online or elsewhere, none of this points to HIV. Every symptom that can occur with HIV, including EVERY ONE OF THESE occurs more commonly with conditions other than HIV.
"Medical literature relates this to late stage hiv" but also to a large number of other conditions. Your test results PROVE that HIV is not the cause in your case.
"however another Dr has said that above test is useless after this period of time": I'm not sure which test s/he was referring to, maybe PCR? Either s/he was wrong or you misunderstood. All the tests you had would be positive if you had HIV. "no idea what limit of detection was': Doesn't matter. Negative PCR proves HIV infection is absent -- or, in infected person, in total control by the immune system or antiviral treatment.
"what other test can I go for?" No other tests are available or necessary.
"I am really worried Dr." Re-read my closing comments in your earlier thread, which include "That you "can't move on with [your] life at the moment" is a cri de coeur that indicates a level of emotional distress that demands professional counseling. It simply is not normal to remain as anxious and fearful as you are in the face of the overwhelming scientific evidence that you do not have HIV and the repeated, reasoned, science-based advice and reassurance you have had from your doctors and this forum. I advise mental health evaluation and care from compassion, not criticism. Please take it seriously."
I hope repeating these facts will finallly help you move on. Mostly I hope you'll in fact follow through with counseling. Either way, there is nothing more this forum has to offer you.
