I was born with spoon shaped nails and had a problem with my kidney. The doctors said that the problem with my kidney disappeared soon after I was born but my scalp was also producing puss that lasted for about a year. My nails are now completely flat as well as small/wide as apposed to long and narrow. They're very soft and bend easily. Dark pink lines have recently appeared horizontally on the nail bed and some have slowly changed shape into a wavy pattern.
My toe nails are completely flat as well. Very small, brittle, and a few are spoon shaped. My pinky toe nails barely exist at all.
I've been to my family doctor, a dermatologist, and a nutritionist but I cannot seem to get a valid diagnosis from anyone.
