Sorry that happened, Frank. I know the more sensitive areas of skin or membranes are greater affected by ficin, the protease (enzyme) in fig sap/latex that breaks down proteins. I know when I do air layers, the skin under my fingernails gets really raw as it is more sensitive than my hands. It stings and eventually subsides, but it is not a lot of fun after setting the air layers- even after rinsing them well. I have also heard that the tolerance to ficin deceases as exposure increases. I'm not sure if this is true or not, but I know the sap didn't really bother me when I first started working with figs, but now it is really annoying with prolonged exposure.
