I just called the doctors office about my missing part of my lip, because my lip is getting thick- numb, blah, blah. When she took out the stitches she told me to do lip exercises-but not for how long-how often. Just to loosen up my lip. I just called her office--- When I got where I could eat pretty good, I sort of said good-bye to the exercises. It sounds stupid, but my face feels tired-and that makes me feel tired. The exercises are to keep scar tissue from forming inside and creating future problems. I wish that she had told me that. My lip is getting really thick.
