Follow-Up:
Six months ago my lips suddenly began swelling and burning to the point where the upper layers of skin would wipe off when I tried to apply chapstick. My doctor thought it might be that I am not getting enough water or a lack of vitamins, but so far nothing helps. They are so sensitive (generally after a day of swelling) that if I am eating something and the sauce gets on them they sting from the chemicals. I don't think I have any allergies, and have no idea why they are not getting better. help
