Hi ! Well about 3 days ago i had mangos and right after eating them instarted to have these tingly feelings on my lips . ( mind you i had mangos before and nothing happen) . It started forming little bumps on the side of my lips . I went to get a cold sore gel called campho-phenique . ( i thought it was a cold sore ) . When i woke up the next day my top and bottom lip was swollen , flaky , itchy and yellow crust . It was dry and you can see the dry skin comming off and it felt like sand paper with little bumps . please let me know asap what this is !
