You can tell you have this foot condition if the bottom of you foot looks damp and soft. I like to call it dish pan feet. I use this analogy because my hands used to look this way when I had to do dishes for a long time. They were damp and painful.
Many times you will have little holes on the bottom of the foot. If you treat it as a fungal infection of the skin using an anti-fungal cream you will not have much success. The treatment of choice is topical erythromycin gel to apply on the skin twice a day. The medication should clear up the foot problem. Of not a steroid cream or biopsy would be a good idea.
To your health.
