Hello I am 40 years of age and I have lost over 80 lbs over the years. I suffer with lower lumbar herniated disc that can be painful at times. I did a tummy tuck 3 years ago and is in the process of getting ready to do a buttocks lift to get rid of the skin and add a little bbl. The buttocks lift involved removing skin from the back so I wonder if any nerves will be damage that will make my disc situation and siatic nerves worst?
