10. A Dark Band on Your Nail

Band On Nail

A black line running up and down the length of your fingernail may be a sign of melanoma. This rare type of cancer is not caused by sun exposure. However, the American Academy of Dermatology lists a family history of melanoma or trauma to the nail bed as risk factors for this type of cancer. Other symptoms of nail melanoma include pain, drainage from the nail, and nail cracking or splitting. Additionally, the skin surrounding the nail may take on a different color than the rest of your skin. Contact your doctor if you notice any of these symptoms.

9. White Fingernails

If your fingernails have turned mostly white with just a narrow sliver of pink at the top, you may have a condition called Terry’s nails. White fingernails may be a sign of liver problems. Studies report that Terry’s nails are linked to diseases such as hepatitis, liver failure, congestive heart failure, and kidney disease. Lindsay’s nails is a condition in which the bottom half of the nail appears to be white while the top half appears to be pink or brown. This condition may be a sign of kidney disease.

8. Nail Pitting

Nail Pitting

Pitted nails may be a sign of psoriasis. Psoriasis in this area may appear as tiny little dents or pockmarks in the nails. It may also cause the fingernail to become brown, crumbly, and loose. If you suffer from psoriasis on other areas of your body, check your fingernails to catch early signs of nail psoriasis. Nail psoriasis can be challenging to treat. However, the American Academy of Dermatology reports that there are many treatment options available to prevent the condition from worsening.
