Is it normal to have prolonged numbness after Voluma fillers? 2 days post op.

The right side of my face immediately went much more numb. It felt like dental block, but several hours later it was gone. However, some numbness returned the next day but went away. On the second day the numbness returned and was severe and lasted hours. It still hasn't gone completely away and keeps coming and going in levels of severity. Could this be nerve damage? What should I do? It's very uncomfortable and at times extremely painful. Thank you for any feedback!!
