I have swollen lips and very itchy, specifically around the very outside of my lips. This is about the 5th time I have had this happen in the last year. I feel like it is an alergy. I have tried taking an antihistamine and it does not help. My lips are so itchy, and dry, but lip chap or vaseline do not help. Little bumps just around my lips, mostly on my lower lip. I have not changed shampoo, or face wash or anything recently. What can I do.
