Luv 'in Austin, that brown cloud DOES do damage to your body. Just this summer, I had a "funny looking" chest xray. My internist sent me for a CT scan and then to a pulmonary dr. to look at it. It showed an area of calcification in one lung that probably is scarring from repeated infections like bronchitis. As soon as the pulmonary doc saw that i had lived in Arizona, he said, "Do you know what Cocci is?" I certainly do know what it is, and although I never thought I had "Valley Fever," I guess I must have had it, when I though it was something else. I guess it just took 15 years to show up.
