I'm 40 years old, I've had 4 full term Pregnancies ( fairly large babies) 3 csections. I now have a large saggy flap that has no feeling in it which I have cut and caught in the zipper .. I'm interested having it surgically removed and I'm curious to what the medical requirements are.. I weigh 250 and I do not have health problems beyond asthma ...And what the average recovery time would be .
