Around 30 percent of people with psoriasis also live with psoriatic arthritis (PsA), according to the National Psoriasis Foundation. Because these conditions so often occur together, the two are collectively called psoriatic disease.

If you have psoriasis, it’s important to know the symptoms of PsA. That’s because PsA can lead to joint damage and other complications that may really affect your quality of life and overall health. By recognizing the signs early, you can start treatment, reduce joint pain, and prevent complications.

Symptoms of Psoriasis vs. Psoriatic Arthritis

Psoriatic disease is an autoimmune disease, meaning the immune system is mistakenly attacking normal, healthy tissue in the body. In psoriasis, the immune system is targeting the skin. As a result, people with psoriasis may have raised, scaly plaques with a silvery sheen on the skin. These plaques appear red on white skin and purple on skin of color.

Psoriasis plaques often appear on the elbows, knees, scalp, and ears. However, certain types of psoriasis may affect other areas, like the armpits, genitals, or scalp. Plaques aren’t just a cosmetic concern: They may itch, burn, or sting.

For people with psoriasis who also develop psoriatic arthritis, the immune system starts to attack the joints as well. In particular, it attacks where the ligaments and tendons attach to the bones. Symptoms of PsA include:

  • Pain, swelling, and stiffness in the joints
  • Stiffness that is worse in the morning or after periods of inactivity
  • Restricted mobility
  • Fatigue
