Each of your 3 tests and her 1 were conclusive so only 1 of the 4 needed to be done for you to confidently move on. At this point, knowing that, it will be abnormal if you test again. Doctors can't diagnose hiv from symptoms so no one here pays attention to them, which is why you should stop studying your body cold turkey and stop googling symptoms cold turkey as well.
Some of your symptoms seem minor, so they might even be in your imagination. For example, you don't know what your lymph should feel like so should stop poking and irritating it immediately. If you wanted your tv fixed you would not go to your barber, similarly see your doc if you want your lymph nodes examined rather than trying to perform self-diagnosis.
On the other hand, anything that hurts should be looked at by a medical professional (or if you are referring to a back ache when you say "now..inflamed ..hurting" a physiotherapist may be able to assess that situation) so I would get them checked out.
You had an actual risk (we see a lot of non risks and over worry about those here). But testing for HIV is reliable and you've had three tests that all say negative. You can definitely stop testing and rest easy that you do not have HIV. Could it be that your prostate issue is back? I'd see the regular doctor about this and please do NOT fear HIV as that is not the reason for your issues (all three tests taken in the appropriate time period to be conclusive tell you that) so get to the bottom of this looking for the REAL reason. There is also a men's health forum here. But do not ask about HIV as that is answered strictly on this forum. You would want to tell your symptoms and say HIV has been ruled out as it has.
