NAIL RIDGE FINGER: A SINGLE HORIZONTAL FINGERNAIL RIDGE IS HARMLESS.
IT DEPENDS ON WHICH NAIL, WHEN IT BEGAN, WHAT HABIT DO YOU HAVE WITH THAT PARTICULAR NAIL, AND MORE OF A HISTORY.
IT SOUND BENIGN AND HARMLESS.
IF YOU ARE CONCERNED, SEE A DERMATOLOGIST.

Injury: Trauma and some illnesses can do this. Remember that nails are related to hair but grow more slowly so that an injury to them may show up over time.
I often see this in my oncology patient with certain chemotherapy. They well have lines in the nails.
