I have had it done, and can tell you it is very painfull for a long time after the surgery. The recovery is 6 weeks, which means you cannot sit properly for the entire period! I was not told that to start with, and subsequently lost my job as could not come back to an office to sit for 8 hours straight.
I had follow up problems, like severe diarhoea and for the first time in my life have developed piles.
This was a preventative surgery, where I went into the hospital healthy, and came out very ill, and 2 weeks later I am still suffering A LOT.
In retrospect, if I new 5% of what I know now, I would NEVER have done it.
I sincerely hope it helps.
