Indentation of Left Flank? Can this problem be resolved?

I have a horizontal indentation of my left flank muscle after having had lipoabdominoplasty. The muscle bulges and there is a horizontal wrinkle underneath it, approximately 3 inches in length. I have been massaging it for weeks, but I don't see any changes. I wore my compression binder for 5 weeks, only removing it for a shower. I'm not sure if my compression garment created it, or the garment reduced the swelling so now I can see it? Can this problem be resolved?
