No Terry's nails, myself. Could it at all be related to elevated liver enzymes like what Cheer has described?
Terry's nails is a physical finding in which fingernails and/or toenails:659 appear white with a characteristic "ground glass" appearance, with no lunula. The condition is thought to be due to a decrease in vascularity and an increase in connective tissue within the nail bed. It frequently occurs in the setting of hepatic failure, cirrhosis, diabetes mellitus, congestive heart failure, hyperthyroidism, and/or malnutrition. Eighty percent of patients with severe liver disease have Terry's nails, but they are also found in patients with renal failure and are described as a brown arc near the ends of the nails.
Hyperthyroidism stands out to me, since jugulars' collaterals drain through the thyroid and maybe can cause thyroid issues.
