I am a 25 year old female. I weigh 125 and am about 5'1. About 2 or three months ago I was attacked by wasps and had to run down a mountain barefoot. After that I had two dry patches of skin on hte bottom of my right foot. One was on my big toe and it was cut open and dry. The second was on the upper part of my arch. I cut away the dry skin on my toe and it healed fine. The one on my arch, however, has not healed yet. It is red under the skin and it had a small dry patch in the middle. I have not been able to remove the dry skin. Now it is starting to itch really badly. What do you think it may be, and how do I get rid of it?
