my lips and mouth have dyskinesia -as the day passes my lower jaw caved in like an old person without dentures and i look like a bird. The only thing i can do is botox but i don't want to look like angelina jolie without a chin.....anyone have any experience with it in the face. This could be tardive dyskinesia; it strikes the lower face and jaw. i had tmj and had to get a device..cost a fortune. but it does go away first t hing in the morning and is caused by meds. may be permanent.
