From my experience and others that I have read on here, I would only have denervation if:
1/ You only have testicular pain after vasectomy
2/ You have testicular pain due to some other reason
I would not recommend denervation if you have pain in the vas deferens and the pain seems to spread everywhere - back, legs, hips etc after vasectomy. This pain could be nerve pain and it seems like it would make sense to block or cut these nerves, but in my situation it only made the nerve pain worse. I’m not sure if this is due to the inflammation and/or scarring from the denervation, or the nerves growing back and being more sensitive, but my nerve pain actually got worse 6 months post surgery and every day since.
I was in a position where I would do anything to get rid of my pain. Looking back I should have opted for pain modification and making changes in my life instead. Anyway just wanted to let you know that nothing is a guarantee in life and in some occurrences, can make things worse.
