Please respond

So about two weeks ago I got hit during my grappling practice and I am a hypochondriac so I google up if it's dangerous and I got testicular torsion so I started to feel my testicle for days squeezing them and trying to find if my spermatic cords are twisted even touching and squeezing my cords not every time l'm about to masterbate when I'm about to climax my left testicle hurts please help me what could it be it's not swollen and it's in normal position and it moves so it's not mobilized
