Yep. had mine done about 10 years ago. You'd be better off shaving your bollocks before the operation. I had to wear some of those paper undies, I got wheeled down to theatre, I was expecting just a quick procedure by a guy in just a room, but no! I had nurses and a female surgeon looking down and working on my nuts.
I remember the worst part, was the injection in my right bollock, you do feel that I'm afraid and you can feel quite a bit of tugging going on. I remember thinking I'm glad my injection is over, but no! They then have to work on the other bollock, so it's one more injection on the other side I'm afraid!
After you're finished, they spray this antiseptic stuff over your nuts, they said it can sting quite bad, but tbh, that wasn't that bad.
After the operation, I went back to my room and I felt fine, obviously a bit sore, but once I had a piss I was free to leave. I started walking down the corridor thinking oh I'm fine, but after about 50 yards or so, the aching started.
I work in an office, so I was back in work after a couple of days, obviously if you have a physical job, I would take maybe a week off work.
The next day after the operation, I remember my bollocks looking like giant melons, but not yellow in colour, they went purple. it would be quite good to walk around wearing some nice speedos as you'll have a massive packet for a few days.
What I also did was to bathe putting some antiseptic lotion in the bath, just to soothe the discomfort, don't put bubble bath in though, as you'll want to keep on looking at your giant purple melons.
Good luck, I don't regret having the snip!
