Sometime the beginning of June, I developed a patch of what looked like poison ivy on my left
foot. It appeared as itchy, red, blisters that oozed and I was treating it with calamine lotion and hydrocortisone cream. About 3 weeks later, the patch dried up and only appeared as if it was dried up skin. Since then, the patch has came back, but with no oozing. I've sat in pools with chlorine that seem to dry it up, but the patch keeps coming back. My biggest irritation is the itching.
