my fingernails turn completely white occasionally then return pink then get white again, is this a nerve disorder?

No: This sounds like raynaud's phenomenon which is a blood vessel problem. Generally it is not dangerous unless you spend time out in the cold. You need to be very careful about keeping your fingers and toes warm. There are medications that can help the problem.

Reynaud's?: Would need a bit more information. Are the fingers cold and painful?
