Filler in nasolabial fold; not dissolving, area getting increasingly hard and lumpy after each hylenex treatment (Photo)

I received nasal fold filler about two years ago. From the day I received it and still today, I feel it in my face, along my gum line and when i touch It. It was placed with a cannula & above my folds making them deeper and basically causing a problem that was never there to begin with. Ive had 6 hylenex treatments, and the filler is still there and getting harder and thicker. feels too firm to be inflammation. Im afraid to cont. w/ hylenx but I want it gone. Will more hylenex make it worse?
