I'm 7 months post op and just started to get some tiny movement back about a month ago. Last week I saw Jackie Diels in Madison and learned a few things that sound similar to some of your experiences. She said that she sees some "life" coming back to most parts of my face. But as the nerves come back, my facial muscles have really tightened up, making my face look puffy sometimes, pulling my mouth into a little bit of a scowl, and making it difficult for my face to move. The muscles kind of cramp up, creating sore spots. She gave me lots of stretching exercises to do to keep the muscles looser and recommended heat.
She also said I'm beginning to get a little bit of synkinesis. When I try to pucker my lips or smile (which I can't do too much but the movement is just starting to come back), the muscle under my eye contracts and my cheek pulls up. I still can't quite drink without dribbling because the synkinesis causes my cheek to pull the corner of my mouth back. She emphasized the importance of very small movements, not trying to force anything. The goal is balance and symmetry.
For now, she wants me to just do the stretching exercises. As the nerve continues to heal, she said my facial muscles will continue to get tight and that I might notice it in different places. I should just try to keep up with keeping them loose. I'll see her again in six weeks and she said she'd be better able to tell then how quickly she thinks it's coming back. Eventually, she said she thought I'd be able to learn to control most of the synkinesis, but I had the impression it is something I'll be working on for awhile!
