This is my now my 13th week after having Tumescent Lipo. I had a seroma that lasted about a month & a half that I had to continuously have drained. The hardness developed about a week or 2 after surgery & has yet to go away. My upper abdomen now protrudes out past my lower & is very hard. I have read online that massage can help, but people have mentioned lymphatic drainage, ultrasound, Endermogie, & synergie massage & quite frankly I'm confussed because some of these are cellulite treatments.
