My right ankle has a dry hard layer of skin over it, it is sometimes dark and has a circle around it. The skin is dead, I can pull it off and feel nothing until it bleeds. Sometimes it is flaky. I have seen two doctors about it and neither can tell me what it is. They tell me to try moisture cream. One doctor told me it was from swimming too much, but wouldnt I have it elsewhere if that was the case? I have tried creams, oils, gels, nothing works. Even removing the skin, it grows back the same. I dont wear anything that rubs against my ankles besides socks. Im always getting asked whats wrong with my ankle and I cant explain it and its embarassing.
