Certified plastic surgeons interested in bbl after silicone injections; best course of action for optimal recovery? (photos)

6 yrs ago I made a poor decision to have silicone (oil) injected into my buttocks which my body immediately rejected. I went to the hospital due to leaking and there I contracted a staff infection. I was released 3 days later and treated with antibiotics. I had cellulitis while on the antibiotics but have not had issues since. The treating doc recommended I get fat grafting but it was all still new so I declined but now after back to back births, saggy booty, and huge abdomen I need sx help!
