Within the last month I've had four allergic reactions that are limited to my lips, skin around the lips, and chin. The area becomes inflamed, chapped, cracked, painful, and itchy. No other area is affected. I couldn't figure out what was causing it because I was eating different foods each time it happened. I started doing some research, and I was looking up common fruit allergies, since I eat a lot of fruit. Lately (in the past 5 months) I've been eating a lot of mangoes. I came across an article about mango allergy and the symptoms fit pretty well with what I’ve experienced. However, my allergic reaction does not happen immediately when I eat the mangoes. This last time, I had eaten a mango the day before. The same is true for the other occasions; I had a mango either a day or two before the reaction happened. Is it possible that the mango is causing my reaction a day later? I have a rash right now, and it has lasted three days. It's easy enough to quit mangoes, but I'd really like to know the cause.
