I had a seroma incised after a thigh lift, it was the size of a golf ball on my outer knee. I packed it for 11 days then ran out of packing so I put a bandaid on it and it started to closed almost immediately. . I am wondering if it will get infected later because I didn't pack keep packing it. It closed so fast I am hoping no infection occurs in the future. What do you think Doctor. Tina
