Life-saving warnings your nails are sending
Dark Stripes
Dark stripes that run vertically down your nails can be a sign of Subungual Melanoma, a vicious form of cancer.
Nail Clubbing
Nail Clubbing is also called Watch-Glass Nails or Drumstick Fingers. It can be totally harmless, but could also be a sign of Liver Disease, Inflammatory Bowel Disease or Heart Disease.
