I have been putting off 2 surgeries since 2010, one is cosmetic and the other one although needed I can live without (for now).
Sadly the one I need will put me out of action for a few weeks, not only that I will be unable to drive too or exercise for a while, I think 6+ weeks and I may not be allowed to lift for a year . My solution was simply to put them off until I reach my goals, fortunately I am so close to the finish line now that I can smell the anaesthesia ;).
The surgery itself doesn't impact my programming projects for long, but it does massively affect all my physical tasks for a long time which is disappointing
Good luck with your recovery
Life's too short, I'd just go for it and get it over with if it impacts your life at all. I had brain surgery and was typing and surfing the web from ICU within hours and went home after 2 nights.
Here's a pic of my scar I took last night, I'm not even taking that many painkillers anymore and it doesn't hurt too bad.
The surgeon gave me a pic of the problem, hard to know what it is but it's crazy that they sew stuff up in there:
