UPDATE (my personal situation and experience):
My burning pain (like a stab in the nutts) during orgasm disappeared completely after 4 weeks (Thank God!). Testicles were swollen and sore for about 6 weeks. I did an ultrasound (6th week) and there’s still a little “liquid” in the testicles.
7th week: Sometimes, I feel a little bit disconfort in the inguinal area, but the testicular sore and swelling are much better, and the ejaculatory pain disappeared.
I thought the pos-op was going to be much easier, it requires time and patience…
