Swelling in thighs and calves after liposuction in tummy, flanks and hips?

is it normal for the legs (from thighs to ankles) to get swollen after lipo in tummy/hips/flanks? I also had revisions in my thighs but I have noticed that my pants are tighter than previous to the surgery 2 weeks ago. why would I be swollen in the legs after tummy procedure? and why are the flanks feel so hard? thanks.
