For the past three years, I have had a very itchy skin rash which has taken on different looks as time progresses. Doctors have told me it was eczema. At one point about 2 years ago, my eyes had little pads formed around the socket areas and these weeped along with my eye lids. Now, for some reason unknown to me, any time I accidently scratch my skin or my puppy digs me, or I scratch my itches, it turns a quick purplish which takes for ever to go away. Then it looks blackish/brown. About the time my arms finally look almost normal, itchy patches pop up and away we go again. I had my water well checked for possible natural gas contamination from a well about a mile from me but the "footprints" tests proved negative. The representative did tell me that it didn't necessarily mean my well wasn't contaminated. I do have lead in my water. That I learned from another test. I can't help but wonder if this is some type of cancer from an internal problem or what. Any suggestions would be very helpful. I thank you. Patricia D. Fiske
