@feruze-- Be careful! You should avoid mangoes completely. My mango allergy started with a lip rash as well and when I consumed a candy with mango in it, it developed into a full face rash and my tongue also became swollen. My lips, my hands and feet very itchy too.
I had to be taken to the hospital, my husband was scared that my throat would also swell up and I wouldn't be able to breathe. I was given a steroid shot there and then I was given additional medication in case I developed the symptoms again when I got home. It was very scary. There is no fooling around with allergies!
