A little help please.

Cross post.

Ok ladies please no bashing im a little concerned.

Lastnight I had a itch on my neck and decided to check and noticed a mole I've never noticed before. I decided to ignore it and move on. Well today I was looking at my nails trying to think of a color to paint them when I noticed I had a brown longitude stripe from the bottom to the top of the nail. Its on my left index finger and one on my right thumb nail. My question is should I be concerned or is this normal?
