Does migrated lip filler take longer to dissolve on its own? (Phots)

I received 1 syringe of filler in my lips 18 months ago. It looked fine, but 1 day later, I punched myself in the lips, causing the left side to droop and swell incredibly large. After a few days, the swelling went down, and although that side of the lip seemed to droop more, it was less noticeable. However, the right side of the filler has now completely dissolved on its own, but the left side remains hard and droopy. It also seems there is volume above my lip line. When I talk, it looks ducky.
