What are the symptoms of nail psoriasis?

Dr. Mehmet Oz, MD
Cardiology (Cardiovascular Disease)
Some of the common symptoms you may see if you have nail psoriasis include:
  • pits or holes in your nail
  • nail thickening
  • abnormal nail shape
  • discoloration
  • nail pulling away from the skin
  • white spots under the nail (which can be a sign the nail is pulling away from the skin)
  • crumbling nails
According to the National Psoriasis Foundation, nail psoriasis affects up to 50% of people living with psoriasis. 

Ninety-five percent of cases of nail psoriasis accompany general skin psoriasis symptoms. In these cases, people will experience cracked skin that might bleed; red, irritated patches with scaling; itching or burning; and joint soreness. In nail psoriasis, individuals will also experience tiny dents on the surface of the nail, otherwise known as pits, and the nail begins to change color - often a yellowish-brown. Nail psoriasis may also cause abnormal nail development, thickness of the nail, and a crumbling or separation of the nail from the body.
