Discolored finger nails
I have seen a lot of information about discolored toe nails, but I have discolored finger nails.
My middle finger nail was dark and discolored and now, it seems to have slowly spread to my ring finger too.
Is there a over-the-counter topical treatment for this?Also, my feet burn a lot.
I do not wear shoes around the house.
Is there anything I can do to prevent this?
