Hi doctor, I'm a 24 years old female. My lips have been very itchy, burning and swollen all over specially around the corners. The skin around my lips looks very dry and scaly no matter how many times I moisturize. I haven't been eating or doing anything unusual or been to a new place. I'm not allergic to any specific food, at least not that I know of. I never had this problem before, it started a couple of weeks ago, and it's getting worse everyday(biting my lips underneath kind of makes me feel better). My doctor prescribed me to use birth control pills for a month with which she also asked me to use some kind of multivitamins which I totally forgot, do you think this has anything to do with that? Please help me doctor.
