Metasteel, are you sure you might not have touched something allergenic with your fingers and then perhaps rubbed your eye with that same hand? Typically food allergies cause swelling and allergic reaction on the lips, mouth and throat and then, if they progress, turn into an all-over reaction like a rash. I don't think you should be worried about going to the doctor to see about it. A dose of about 50 mg. of Benadryl (diphenhydramine) does wonders toward getting rid of mild allergic responses like yours.
