Can filler to cheek cause pain behind eye?

I had .5 cc of Perlane injected into cheek. That night I felt like I got hit in the face with a brick and punched in the eye. The doctor said he may have hit a blood vessel or bruised the lining of the cheek bone. 6 weeks later I still have pain behind my eye. Been to optometrist and had CAT scan which show nothing wrong. Could the injection have caused this eye pain? Also, my eye appears sunken in and the area by my nose has become flat. Is it too late to have it dissolved? Can .5 cc be dissolved?
