I was going to post asking if anyone knows what fingernail changes mean, what health conditions the changes reflect. I decided to Google it, thought I'd share a few links I found.
This has slides of some conditions. Nothing better than a picture to compare your own nails against.
This two-page article starts with tips for keeping your nails healthy, then has a chart on changes caused by different health conditions.
My nails definitely reflect a couple of my health conditions, though you have to look closely to see it. Which I guess means my conditions aren't too bad... yet.
Please share any advice or knowledge you have, or just your personal experience.
