I am 37 years old male, I have protected sex which I used condom on 5, Aug. On 18 Aug , I was nervous I was infected hiv, I kept prodding my left and right armpit s lymph node for over 30 times within a few hours, I initially felt hurt when I pressed hard and deeply on lymph node, and I got mor nervous, So I kept doing it until was too late. I didn t know I hurt myself or not, I ended up making my lymph sore and swollen, I took some painkiller and now it feel better, the heat and swollen went down a lot. Today, I suddenly feel my hand and elbow were bit painful, when I press to my low part of palm, I feel somehow it was num and more painful, so as a few fingers and I suspected I had Rheumatoid arthritis, which I heard it was also result from hiv. Should I do 4 generation combo test and is it common ars has Rheumatoid arthritis? Thanks in advance
