I had bbl with lipo and I'm 1 month post op. My skin on my stomach sides and back are very tight which is uncomfortable. I have hard knots/lumps on my sides and back and they are painful. I get sharp pains in the areas that were lipo'd .I've had a total of 17 lymathic drainge massage which were all painful by the way and I decided not to get anymore because I just couldn't handle that pain anymore. How long will it take my skin to soften up and how long before these knots and lumps go away?
