1/8" brown vertical line in thumbnails
Recently I noticed a thin 1/8th inch vertical line in my right thumbnail. It is brown/tan and somewhat light, but noticable. In runs the entire length of my nail & appears to only be in the nail (not below the nail). I cut my nail as short as I could and did not notice any color below the nail....but I'm not certain. I have noticed this for the past month or so. Also, very faintly I also have the same vertical line in my left thumbnail in the exact same spot, however, the left nail is almost unnoticable. Neither nail is painful or feels any different than a healthy nail. Any help figuring this out is greatly appreciated. I should note, I'm a 37 year old caucasion male.
