Everytime I eat sandwhiches, fruits like apple, bananas, and drink lots of water. I can feel my lower lip is itchy, and when I scratch it using my teeths, my God it hurts real bad. and when i stop scratching it, I feel the lump starting to grow bigger and bigger....it hurts, when I touch it and I cant bare to look at it...cause its weird. What is happening to me?
