I had Juvederm injection in my chin 9 months ago. Now I feel pain in my chin whenever I press on it?

This isn't typical. I recommend getting a formal evaluation with your injector. If filler is still present, you can have it reversed with hyaluronidase. I hope this helps. 

Hi Chris, It is uncommon for a filler to cause pause 9 months following injection. I recommend seeing your initial injector for an evaluation. Directed Hyaluronidase injection may help dissolve any residual filler, if that is determined to the most likely cause of your discomfort. Best wishes.

I don't believe that the discomfort and what it is you're feeling is associated with your injection 9 months ago. I believe you need an in-person consultation with either the same treating physician or plastic surgeon like myself near you. Good luck from New York City

It is unusual for the pain to begin so long after injection.  If there is filler still present in the area you can choose to have it dissolved with hyaluronidase.  I recommend seeing your injector for an evaluation and treatment plan.
