I guess it depends of size and location, along with the type of procedure. I had something the size of an egg protruding from my groin. I suspect it had been developing for many years as I'd had sharp pain in that region for a long time and had a couple of hospital visits to investigate but was never scanned to see exactly what was going on, so it was spotted late and required open surgery with fairly extensive external scarring which I assume is permanent (not an issue).
I'm no longer in pain but I'm certainly aware that I have something (mesh/scarring) in my groin, especially when making certain movements. Hopefully this will lessen over time.
