I'm glad I found others with the same condition as me. I've gone from dermatologist to ear, nose and throat doctors and they can't help me. I've had this swollen lip for about a year now and I'm going out of my mind as I'm so self-conscious about it. I, too, feel as if I've had botox on my lower lip and now my upper right lip corner is swelling and chapped. I put ice on it every morning for a few minutes and it goes down, but the rest of the day it's very uncomfortable and I've stopped using any lip balm with petroleum as I think additives may exacerbate it. Helpppppppp!!! Should I go to an internist? Thanks.
