Is anyone in the NYC area experienced in treating a late-onset inflammatory response to hyaluronic acid dermal fillers? (Photo)

I have included an article for you to read.  I had treated someone for this problem who was injected elsewhere.  The injections were completely appropriate and there were no problems for several weeks following her injection overseas.   aestheticsjournal.com/feature/granuloma-management

I am assuming that your doctor has already tried to remove this with hyaluronidase. If not, this would be the first step so that the product itself is removed. I would be very cautious about injecting steroids as this can cause atrophy of the surrounding tissue. A course of oral steroids might be worth a try. It could take a couple of years for this to resolve on it's own. Injecting PRP could help speed up the healing. Another option would be to surgically remove it or do a fat transfer around the area to improve the appearance.

A combination approach using cortisone and removing all of the filler with Vitrase is usually the best approach.  I would definitely have everything removed to stop the continued reaction that you are facing.  Best, Dr. Green
