Welcome to the Forum. I'll be please to address your concerns. While AI will provide more details in my responses to your specfic questions, the bottom line is that this was a no risk exposure which did not aven require testing. Your testing however, at tthis time, PROVES that you did not get HIV. Please read my responses below for details:
1 - In the below post Dr. HHH stated that it is impossible to be infected and have a negative PCR DNA test and antibody test after 4 weeks. Is this true? Scientifically or opinion? Why?

The combination of negative PCR test, which tests for the presence of the HIV virus, and a negative HIV antibody test at 4 weeks prove that you did not get HIV. Tests for the virus and antibodies have been carefully studied in thousands of patients during the approval process for so-called DUO tests which test for both the HIV virus as the p24 antigen and HIV antibody and found to provide definitive results at 4 weeks after an exposure. The HIV PCR is, if anything, more sensitive than the p24 antigen. Thus your results are definitive and prove that you were not infected.
2 - Do I need further testing? I have read, & the place I went recommends you follow it up with a 3 month test to be conclusive? Had my jaw swelling & dry mouth been from HIV would my test 1 week after symptoms started have been positive? There would have to be virus/DNA in the blood for it to cause a physical reaction like that wouldn't it? Probably in large amounts?
No you do not need further testing. As I mentioned above, if you had HIV your test would be positive. Further, symptoms of early HIV cannot occur unless the antigen or the antibody were present and detectable. Persons who tell you that you must test at 3 months are being overly conservative.
3 - How common would HIV salivary gland swelling / issues be as far as happening at around 3 1/2 weeks? Is it usually the only symptom?
This is a non-specific finding which is not particularly suggestive of HIV.
I hope these answers are helpful. To repeat, your exposure was no risk and your test results prove that you did not get HIV. There is no need for further testing. EWH
