Hello, I discoverded recently that my face is uneven. I never noticed but in a recent picture the difference is notable. My right size is normal but my left size is more skinny. I started seen pictures from before and now I noticed that I have differences since 10 or 12 years ago. My uneveness is more noticeable now because I gained some weight (before I was really skinny)

can you tell me what can it be or what kind of doctor should I see? Can it be a dislocated jaw or a facial paralisis (i don't remember having any symptoms in the past)
