I always eat apples by cutting them up in slices, but a couple days ago I didn't have a knife so I ate it by biting into it. Now my lips and the skin all around are inflamed, red, swollen, cracked. My tongue and throat are fine, its just around my mouth. This has never happened before, but I usually never eat apples without cutting them up first. I've been using Vaseline lip therapy, should I take Benadryl?
