I woke up yesterday with a bad case of hives all over my face and neck. Today I went to the doctor. She thinks it's something I ate or a medication but I haven't had anything new or different. My face is driving me nutty because it itches so badly. I can't be in the sun and can't put anything on my face. Going around bare faced isn't good for my Avon business.

Does anyone know how long hives usually last?
