I developed a seroma 3 weeks after having a full tummy tuck and muscle repair. A drain was inserted through my belly button and up into the pocket for one week (collecting a total of 60cc's) Two days after the removal of the drain, the seroma returned. Since then it was aspirated four times (only draining 10cc's or less each time), and now I have a Penrose drain in place. The skin is now very loose and I am worried it might stay this way. How long should it take to tighten up again?
