I had one done last year, it was uncomfortable at times, but I found I could do 85% of what I used to, including mild lifting. I used to be a steel fabricator so most universal beams were out.
Mine sort of pushed its way through about a month after the initial strain, which for half a day was quite painful, but a flying visit to the doc confirmed there were no nasty complications and we learned to live with each other.
A strangulated hernia can be life threatening
I opted to have it repaired under local anesthetic which meant I had it repaired quicker as they could fit me in on the end of a standard list. That was no worse then going to the dentist, but I was a student nurse a very long time ago, so the theater environment was not that worrying. I had a nice chat to the pair doing the op', but was miffed they wouldn't let me watch - never saw a hernia repair during training.
Ten months on and it has pretty well settled down, I feel the repair now and again, but thats nothing really. Steel beams are still out, but I am also older so thats probably for the best.
One piece of advice, when they say take it easy for six weeks after the op' DO SO, and then your repair will last. It can be the better part of a year before you are fully healed.
