Contact dermatitis

I woke up yesterday morning with my face red and itchy and my eye swollen. The doctor';s diagnosis: Contact dermatitis. I'm a bit better today, but my eye looked like someone hit me. I have no idea what caused this. She said it does not look like poison oak or ivy, but it's driving me crazy. I can't wear my contacts because my eyes are bothering me and trying to work with my glasses on gives me a headache. I am not hiving fun.
