Hard swollen lumps under eyes 6 months after Juvederm cheek filler

I had juvederm injected high in each cheek to plump out the wrinkles at the sides of my eyes 6 months ago. I had a bit of bruising at the time but nothing else. 6 weeks ago my eyes started looking puffy and this has got worse. 3 weeks ago hard lumps appeared which have got worse. I have intermittent pain above my eyes. my doctor diagnosed sinusitis but Antibiotics and nasal sprays haven't worked. IS this the filler? I've had 1 treatment to dissolve it but no effect 2 days later and I'm worried!
