I had a large chin implant (incision was external, under the chin) put in 3 weeks ago. The pain went away quickly and it looks great. The right side of the chin and my lower lip on the right side have been numb since the surgery and I am slowly gaining back feeling. However, this week I started experiencing some sharp shooting pains in that area and a burning sensation under my lip. Should I be concerned? What can I do/take to reduce the pain? Thanks, Christopher
