I had smart lipo on my chin, abs and back flanks over a week ago and had hardly any bruising. However, I have a deep soreness in my abs and back. I Can hardly even touch those spots. In addition, my abs and back feel really tight, like i am wearing a thick band around my waist (it feels like that even without my compression garmet). I just want to know, is this pain normal, and about how long will this last?
