I had bad pain after my vasectomy and it got better SLOWLY over about 3 months time. For me the pain never went away completely, but did get a lot better over that time. It is hard to imagine healing can be that slow, but it seemed to be true for me. I thought it was going away but then got worse somewhere around 6 months.
My wife was confused when I kept saying I thought it was getting better slowly, she basically said ‘it has been so long, if it is getting better, shouldn’t it be gone by now?’. it is just that the progress was so slow, improvement only noticeable week to week, or month to month, not day to day. It is frustrating, but if you can be patient you may ‘get out’ without more surgery. surgery can be a roll of the dice, might make things worse.
