I have a client who is an elderly gentleman. On his right foot all his toenails are perfect and on the left foot all the toenails have fungus. I have never seen this. Usually I see fungus on the big toe or on a few toes per foot. I was wondering what you thought of this.
This pattern of one foot involvement is not all that uncommon. I have no explanation for this (nor does anyone else, as far as I know). It is curious, but it happens. Usually the foot with the toenail fungus has athlete’s foot, and the one with normal nails does not have athlete’s foot (both are caused by the same fungus). -- Phoebe Rich, M.D.
