Swelling in legs 6+ months post Lipo. Is this normal?

I had Lipo of inner / outer thighs and flanks in may 2017. I healed fast except for leg swelling. Ever since this operation I’ve had erratic leg swelling. immediately after surgery and even 3-4 months PO I get. I’m now 6+ months PO and when I wake up my legs are not swollen and by time it’s evening my jeans are tight and thighs and calves are puffy. I eat super clean , workout, drink a lot water. is this normal and or related to Lipo or perhaps something completely unrelated ? I’m at a loss
