WOW,
was just talking to my sis about nail ridges this morning. I have fibro and cfs. I noticed about a month ago, that I have ridges,not horizontally, but vertically, and only on the thumb nail. Each nail has only one ridge right in the center of the nail. Also its not just a ridge, its something you can feel and see right away. It goes up right into a bump almost, starting from the moon area. Does anyone know what causes this??
