Shar...lip weakness.....Mine was weak too, and it made me so sad, bec. I love to smile and I was disappointed about the lip. My dr. said it would definitely come back...to be patient..and do you know what? It did! slowly, without my noticing it. Be patient. I also did lots of lip exercises and fish lip shapes, trying to stimulate it. I have no idea at all if that helped or not. It is normal now, exc. for the slightest bit of weakness when I try to make a monster face, which is not a necessary part of life.
