Kerry...I would recommend immense amount of water flush, and you could also use eye drops geared toward allergies. I actually use the eye drops before I go work with the figs, and when I get done, and repeat as needed. For irritated eyes/eye tissue, I personally like to apply cold cucumber slices, cool damp tea bags, or a cool wash cloth. The cold cucumber slices seem to work the best for periorbital swelling brought on by allergic response. The tea bags supply tannin which help sooth the irritation, and the wash cloth just is moist.
@Noss...I hate that you had that level of a reaction to the mangoes. That may be worth getting a prescription for an epi-pen, just in case a future reaction goes anaphylactic. You're living on the edge. That being said, I have been cautioned to monitor for allergic reaction to mangoes and bananas, but my skin tests have been negative so far. They told me that since I have a true latex allergy that I may not develop the food related allergy (mango and banana are related to the rubber tree). It got really interesting when my then elementary aged child was having a party at school and someone handed me a balloon to blow up...I was caught up in the moment, didn't stop to think, and blew up the balloon. Then I blew up. Now if I even touch a latex balloon I have a reaction. Anyway....reactions are dangerous and I am so hoping that my fig reaction does not advance any farther.
