What Your Nails Are Trying to Tell You About Your Health

3.Dark Lines Beneath the Nail

Usually resulting in bleeding under the nails displaying either constant black or purplish markings, trapping your fingers in a door can be rather uncomfortable. You should contact a doctor right away, though, if your nails have dark lines or markings under them although you have not lately suffered any harm. This could indicate skin cancer. Medically speaking, these dark streaks—called melanonychia—can be especially alarming if they show up on one nail instead of several. Although some black lines could be benign and brought on by things like medicine, pregnancy, or ethnicity—they are more common in those with darker skin—any new or altering line should be seen by a healthcare provider. Underlying the nail, subungual melanoma—a type of skin cancer—causes the most major worry. Successful therapy depends on early discovery, hence any unexplained dark line—especially one that is widening or darkening over time—should be seen right away by a doctor.
