There's really only so many things it can be. I've had so many different theories since this all began. Fortunately, with my insurance situation, I've been able to pursue most of them. The problem with each of them is they could explain certain aspects but not others. Why would a nerve in my pelvis given me a headache, etc. Another thing that bothered me is how stark a contrast it is between happy vas guys and us. It's either "no big deal I love life" or "holy crap I want to die yesterday."
Several months ago my wife had a vascular surgeon work on some vericose veins. Naturally they started talking about pelvic arteries etc. This doc talked about the pelvis like it was forbidden territory. Said multiple times she'd operate in the skull before the pelvis, talked about the pelvic floor. Just had a lot of interesting things to say. It was eye opening. If only urologists had the same level of respect.
Most guys on here have a traumatizing story to go with their vasectomy. Couldn't get numb, etc. This sounds so nerve related. My nerve damage has spread to my leg. I saw a therapist this afternoon and within 2 minutes she concluded I had a neurological injury.
It's unfortunate, it sucks, I'll live a life of regret, but it's my life now. I wish medicine had a better answer for nerve related problems. Maybe someday.
