I believe my pain is complex but the worst of it is, I believe, coming from the genital branch of my genito-femoral nerve. It is in the scrotal skin and not the spermatic cord. I have drawn a picture of where my pain comes from. I can roll the skin right where I got my original vasectomy and feel the scar tissue.
You can see circled in red where my pain is. Within that red circle I have a vertical ridge of scar tissue. My vasectomy access point was very high on that side. I am now looking for articles about pain in that region. I may look into some blocks to target that area to see if that will help me.
This is the guy that performed my vasectomy.
