Skin rash? - skin rash more condition_symptoms

I know it's asked a strange question in a part of the company, but I have a very severe rash on his hands. It happens to be where my new leopard geckos to climb and I'm not sure if it's coincidence or not. Is there such a thing as an allergy to leopard geckos? Thank you.
