Hello, I had a protected relationship, vaginal sex and an unprotected relationship, oral sex. I did the test 6 weeks after the relationship, a fourth-generation combo in the laboratory, and the results came back after two hours, non-interactive. I know that protected sex does not transmit the HIV virus, but after 6 weeks I feel pain and tingling under the palate and in my neck, and there are small painful glands in addition to a large knot on the right back muscle, very painful, and pain in the joints. My question is 1) Are these symptoms a result of delayed inversion The serum is after 6 weeks, and that is why my result was false negative. Do I have to repeat the test, the remaining two weeks have completed 3 months? Should I repeat the analysis at this time, or is my analysis in the laboratory a quick analysis and not an analysis by a device because the result appeared after two hours or a little less. I contacted the laboratory and they told me to cut after 40 days. What should I do? The swelling behind my neck is very painful.
