The Signs and Symptoms of Psoriasis

The signs and symptoms of psoriasis vary depending on the type you have. Some common signs for plaque psoriasis -- the most common type of psoriasis -- include:

  • Plaques of red, inflamed skin, often covered with loose, silver-colored scales. These plaques may be itchy and painful and sometimes crack and bleed. In severe cases, the plaques will grow and merge into one another, covering large areas.
  • Disorders of the fingernails and toenails, including discoloration and pitting of the nails. The nails may also begin to crumble or detach from the nail bed.
