I came home from work early yesterday because of the pain and had a long hot bath (and read Conrad's Heart of Darkness - bloody brilliant stuff). Then I spent the next few hours sat with an ice pack and lo, this morning I feel a lot better.
I suspect my return to boxer shorts (instead of tight pants) was too early.
To summarise (for all snip candidates):
Op - easy, very little pain except when they repeatedly inject your tubes
Post op - fine if you follow advice, take it easy, tight pants, ice packs
Three days later - don't accept an offer to help dismantle a stone wall with a sledge and pick
Four days later - ignore advice, keep wearing tight pants and applying ice as necessary, they said three days and it wasn't enough for me.
Once the pain is gone it will be on to stage two, the clearance sale of all unwanted stock. I have to deplete my store of sperm. There are two tests, one at four weeks and another at eight weeks (or thereabouts) to see if you have any of the little swimmers left. Technically the next few weeks should be the fun bit :-)
Cheers
