Q. Hi there.i used to have a very defined jawline but over the last couple of years it seems to be deforming. one side is getting thicker and more rounded and the other side feels like the bone is disappearing and there is a lump of bone on my chin, its causes my face and smile to be very asymmetrical and is giving my a very low self esteem. ive noticed that it gets worse after lack of sleep or when im stressed.this may sound weird bu t i can feel its growing/changing and it cause a slight numb pain(only on one side) i have looked it up on the net to see if there is a reason but i cant find anything. its upsetting me greatly. really hope to hear from you
