What are the symptoms of psoriasis?

There are several types of psoriasis. Symptoms for each type may vary in severity and appear in a wide array of combinations. Symptoms depend on the type of psoriasis the individual has and may include the following:
  • Bright red areas of raised patches (plaques) on the skin, often covered with loose, silvery scales. Plaques can occur anywhere, but commonly they occur on the knees, elbows, scalp, hands, feet, or lower back. Nearly 90% of people with psoriasis have plaque-type psoriasis.
  • Tiny areas of bleeding when skin scales are picked or scraped off (Auspitz's sign).
  • Mild scaling to thick, crusted plaques on the scalp.
  • Itching, especially during sudden flare-ups or when the psoriasis patches are in body folds, such as under the breasts or the buttocks.
  • Nail disorders. One study found nail disorders in about half of people with psoriasis. Nail symptoms include: Tiny pits in the nails (not found with fungal nail infections); Yellowish discoloration of the toenails and possibly the fingernails; Separation of the end of the nail from the nail bed; Less often, a buildup of skin debris under the nails.
