Paralyzed Lip After Neck Lipo and Chin Implant

I had neck lipo and a chin implant 3 weeks ago. The right side of my bottom lip feels paralyzed. It won't move at all. Everything that I have read says that the lip funtion will return. I know that it will heal slowly, but shouldnt I see a little improvement after 3 weeks? It feels like the muscle on the right side of my chin just won't move at all. When I smile, the left side moves down, and the right side doesn't move, which makes my smile look very crooked. Will I just wake up one day and be able to move it a little? I just want some kind of sign that it is not permanently damaged. I am really worried. I read that it will heal at 1 mm a day. So after the entire nerve has healed will it start to work, or will it work a little as the nerve is in the healing process? I am a little confused. I hope you understand what I am asking. Thank you. This picture was a few days after the surgery. It doesnt look any different after 3 weeks other than some of the swelling has gone down.
