looking at the nail? do you have a one of your machines because i know you have an entire office full of machines that can detect just about anything. is there a machine that looks at the nail? how do you do this? we have several machines. we use a regular ultrasound machine to show the thickness of the nail. then we use the blood flow to see if there are any abnormal blood flows in the nail and what it means. for example, when you have psoriasis, which is a common nail problem, it not only thickens the nail, but it s associated with arthritis in about one-third of people. so one-third of people with fingernail psoriasis will develop arthritis. and this is something we re just learning about. that s incredible. i saw the list that you sent me. it was 29 different, i guess, abnormalities of the nail that can predict problems or tell you what the history of the body has been in terms of health.
