saranga, it's more commonly known as an overhang. It's where the skin above the incision/scarline hangs over the scar, iyswim. Some get it, some don't: age, weight/fitness (pre-pg and pg) and skill of the surgeon all seem to play a part.
I've had both a VB and ELCS. First birth (vb) was long, I pushed for a long time but the pain was never as bad as I had imagined it to be. I got through it on G&A alone (though if I was to do it again would have insistes upon an epidural because a) I could have rested and possibly slept for several hours instead of being awake and b) I had an episiotomy anyway, so the 'epidurals mean an episiotomy' argument was void in my case!)
I incured a significant tailbone injury that I felt was reason to request an ELCS for my next birth.
To be honest, I preferred the ELCS birth experience over my VB ... but that's because I am comparing my births. In a perfect world, I would have liked to have had both my babies in water with minimum intervention (dd1 delivered by ventouse in the end) and no tears/cuts anywhere. Breathe 'em out.
It didn't work that way. Anyhow, both recoveries for me were fairly long, but I preferred the predictability of the CS recovery.
However, we are contemplating a third child who I would request a repeat CS for and honestly, the idea of having another CS and recovering from it whilst having three children to care for and also being concerned about developing an overhang ... well, I'm very carefully thinking, that's all.
Beware that multiple CSs are not recommended. The more you have, the riskier they become. I think 4 is about the maximum recommended limit.

It's swings and roundabouts. As someone once said to me "there is no easy way to have a baby".
