If you look closely at the above picture—through the flash glare—you’ll see a little white spot on my fingernail. For as long as I can remember, I get one every few months or so. It’s called Leukonychia Punctata, the most common form of random white spots on fingernails. It is usually caused by a deficiency of zinc in one’s diet or mild trauma to the nail, doctors say.

I’m not sure what causes mine. But thanks to an insatiably curiosity and my ninja Google skills, I finally have a proper diagnosis. Ahhh. That feels better. Anybody else get spots on their fingernails?
