6 months post op and have persistent swelling. Is this a normal side effect? (photos)

I had an endoscopic brow & cheek lift in Nov 23. Post-surgery the swelling appeared uniform. In Feb 24 it became more apparent under the eye area creating swollen festoons. I’m 6 months post and it's very swollen. My doctor says it'll go by itself in a year’s time, and he cannot remove it w/ a needle because the liquid is mixed inside my face. I tried Indiba and massages but no improvement. Is this a normal side effect? Should I be worried? What I can to make it go away? Thank you.
