@godfather2 This is a good time to start looking at a medical grade genetic screening. The ground glass is early Cancer, and CAN be a sign of various autoimmune cancers. Nebular Genetics is one of the better DNA screeners, I hear. My ground glass turned out to be Gelsolin (GSN AKA AGel, Finnish Gelsolin). Another fellow here has a different cancer, but the first real sign was the ground glass.
