When I worked at Subway, my allergy nearly caused me to loose three growth cuticles in my fingers. My nails were as soft as the bottom of my fingers, not to mention my skin reacted as if it was immersed in acid. Skin cracking and peeling off leaving horrible open sores and lots of bleeding. Needless to say, I quit that job for health reasons and it took 6 months for my fingers to fully heal.
