I had mine done in 2005. It hurts a little during. Afterwards more so. Frozen peas and corn will be your friend. Abstain from sex until dr says so. He/ she will have you blast in a cup a few times to measure sperm count or lack of.
I did have complications with mine years later. I developed a cyst where the Vas Def was separated and had to be cut open again. But this was a rare condition as per my Dr.
good luck.
