Is wearing Spanx instead of the garment 8-days post liposuction okay?

Today I removed my stitches and looking at the big mirror I noticed my right side has a bulge looks like fat (I hope not) right where the garment was creating a crease. I tried straightening the garment but it just creates creases I think the issue is my torso is too short I bought another one from another brand and still same issue it creates creases so then I remembered my spanx when I wear it it's so smooth so I went and changed into that instead, is this fine or can it damage my results?
