Question:  I think I have toenail fungus, but it's only on my big toe and little toe.  Why is this?    

Answer:  Great question! It has to do with tight-fitting shoes and repeated "mini-traumas" to your nail plate.  As you step, your toes repetitively hit the end of your shoes gradually separating the nail plate from the nail bed.  This allows fungus to creep into the nail bed and start growing.  We see fungal nail growth more frequently in a patient's big and little toes because these toes get the most pressure from the sides of tight-fitting shoes and thus they experience mini-traumas more often than the other toes.
