Can a filler go down from a big hit on the cheek? Got filler on the outer cheeks 3 weeks ago

I was vacuuming with our new vacuum and the suction is very strong, one of the parts came off while I was holding it and it hit me very very hard in the cheek, was very painful and think will bruise. My right cheek, where it hit is just under the bone. From the end of my right eye if you go down 3cm, just under the bone. My right cheek looks like it has shrunk ? ? Is that possible ? It doesn't look symmetrical. I got filler 3 weeks ago on the outer cheeks, but after the big hit looks smaller.
