Skin necrosis after liposuction - 3 weeks post-op. (photos)

Hello I had liposuction three weeks ago. In Miami by a board certified surgeon. At first I was applying triple antibiotic ointment and changing the dressing. The smell was so bad......after researching I had a feeling it was necrosis. I have sickle cell disease, and never smoked. Today my doctor said it is in fact necrotic, and cut out a portion of the dead skin, told me to pack it 3x a day. My question is should I see a wound specialist. Any thing I can do to heal with minimal scarring?
