Vertical lines on finger nails

Answer 1

Splinter hemorraghe is caused by voids in the nail cell production which fill up with blood from the nail bed. They do not run the entire length of the nail plate, but will grow forward with the nail plate until they grow off with the free edge.

Melanonychia are vertical pigmented bands, often described as nail 'moles', which usually form in the nail matrix. Seek a physicians care should you suddenly see this change in the nail plate. It could signify a malignant melanoma or lesion. Dark streaks may be a normal occurrence in dark-skinned individuals, and are fairly common.
