itchy fifth toe spreads to other toes
One year ago I had an itchy fifth toe; in two months it spread to blisters between to toes which eventually broke and formed a callous which peeled off easily. At the same time itchy fingers and into the palms of my hands, and on ball and my foot, some on the left foot. I used vinegar water 2x a day, also cortizone 1 % Eventually it disappeared for at least 9 months...now it is returning.
What shall I do?
