Dermal fillers hard and swollen 4 months after - could a granuloma form that fast?

I’ve had fillers for 3 yrs. 4 mon. ago had Restylane under my eyes. Got covid the end of Nov. 2wks later had sinus infec. my filler was tender & swelled slightly. was back to normal within 4days…9days ago started to swell again. very large & firm. My whole face will swell for a couple days & then go down a bit. filler stays hard&large antihis prednisone antib’s do nothing. injector said dissolving that big of an area wld ruin tissue. day to night swell pics.could f.b. granuloma form that fast?
