It was fast and painless. I got sore the following morning, but nothing too bad. You just get that uneasy knot in your lower stomach like someone kicked you in the balls. Your balls swell a little bit, but nothing outrageous. I felt well enough to workout (lightly) by the third day.
The only weird thing is the procedure. You're sitting there in a dentist chair, facing forward, they have your junk pulled through a hole in a surgical sheet. Like a pair of plums on a picnic blanket. You have the doctor on one side (facing you) and the assistant on the other side.
So, you're sitting there making small talk with them while they efficiently make incisions in your ball sack, locate the little white tubes, give them a quick snip and then tuck them back in and sew it up.
The whole thing was done in like 20 minutes. The guy who worked on me says he does 1700-2000 a year.
