Fingernail issues

The last couple of days I have noticed horizontal indented lines on a few of my fingernails that I haven’t noticed before. I’m curious how many other chiarians have this as well…

I also have the vertical lines in my nails. I never noticed it before, however I don’t know if it is related. There are like 38 disorders that can go hand in hand with chiari. It may have something to do with one of those. I don’t know. Good question for a neurologist.
