How can I get rid of excess swelling at tip of chin (after numerous chin reduction surgeries - sliding genioplasty 20 years ago, tissue reduction procedures, rolling of chin muscle, liposuction) that will not go away after surgery. Scar tisue has caused lack of lymph drainage in this area obviously. Kenalog works for 4 months at a time then swelling comes back. The last surgery was 3 years ago. Please help!
