This has probably been done a million times already but I ran into a explanation of what happens after vasectomy. The Wikipedia link is good https://en.m.wikipedia.org/wiki/Post-vasectomy_pain_syndrome
but this one explains it really well. Kind of a road map as to what I’ve gone through these last 18 years. To a tee. Right to the granulomas etc. If you google post vas then you probably have seen it. I just had to comment on accuracy compared to what I’m or we are dealing with. Have a look.
