I had lipo in my abdomen and flank areas about 7 years ago. I never got the flat results I was hoping for--I have some firm lumps that may be scar tissue as well as a dent where too much was removed. I've tried lymphatic drainage, warm sculpting, Sculptura injections. Nothing worked. I'm considering a revision BUT Ive also had persistent nerve pain (stinging, burning) since the surgery. Is post-lipo neuralgia common and will a revision make it worse?
