I had the same thing for 5 months, treated with a month of invecterin, eurax, and several different chemicals applied to the skin which I found on UCLA dermatology website , if you still have them or want to talk about, I had doctors give up and say it was in my mmind etc, but other people saw the marks on my skin and my cats got it also.I did finally cure it, but was very difficult, email me at sleetsnow. at AOL
