Hi! I would definetly see a physician about the fingernail issue and possible nail fungus? I know in my fingernail experience I had to see my GP then a Dermatologist for treatment. Also, if you are not allergic to latex I would wear latex gloves or plastic gloves when exposing your hands to the harsh chemecials or detergents until you decide rather to seek medical advice from a medical practitioner. Best of luck and hope that you find a cure or answer from a medical practitioner, best wishes krzyk101
