What is happening in the skin?

Psoriasis causes skin cells to grow too quickly and build up on the surface of the skin. These extra skin cells form thick, silvery scales and itchy, dry, red patches (plaques) that are sometimes painful.

Psoriasis or something else?

The symptoms of psoriasis can be difficult to distinguish from those of many other skin conditions.

Some of the more common symptoms of psoriasis include:

  • raised, red, inflamed lesions covered in silvery scaly plaques

  • small, red, individual spots

  • dry skin that may crack and bleed

  • itching, burning, or soreness of the skin

  • thickened, pitted nails or separation from the nail bed

  • swollen, stiff joints.

Psoriasis affects everyone differently, and it’s best to have any symptoms checked out by a doctor when the following signs are present:

  • progression beyond the nuisance stage, causing discomfort and pain

  • makes performing routine tasks difficult

  • causes you concern about the appearance of your skin

  • leads to joint problems, such as pain, swelling or inability to perform daily tasks.
