For the first week doc said no erections- turns out not getting hard was the hardest part. After that, it was like a month or so of no unprotected sex. It's been a few years so I might not remember correctly, but I think he recommended like 15 to 20 ejaculations in that time frame. And I'm going to humble brag here- I've been blessed with a wife whose libido is way higher than mine. But that month, knowing that each orgasm was one step closer to her not having kids again- she made it her mission in life to knock those orgasms out as fast as I could get it up.
I didn't really have any swelling that I can remember- I iced my scrotum for a few hours but it didn't hurt too bad so I stopped after that. Some acetaminophen helped with the residual pain, and I think I had to take it easy for a couple of weeks- don't lift anything heavy to strain your groin muscles.
All in all, I don't regret it and highly recommend anyone who is done having children to get one.
