Understanding PsA

Chronic inflammation causes symptoms including
joint pain & skin plaques.

Psoriatic arthritis (PsA) is a chronic inflammatory disease that occurs when your immune system mistakenly starts attacking healthy joints and skin. People may experience joint pain, difficulty moving, and skin plaques. If left untreated, permanent joint damage may occur over time with PsA.



The overactive immune response causes inflammation that can trigger joint pain, stiffness, and swelling as well as red, scaly skin patches called plaques—caused by excess inflammation.

PsA is different than rheumatoid arthritis.

It can be confusing to know if your symptoms are related to PsA or rheumatoid arthritis because the characteristics are similar. One key difference between the two is rheumatoid arthritis does not present with plaques where PsA often presents alongside plaques on the skin.

Only a doctor can provide a diagnosis. Talk to your doctor about the symptoms you are experiencing.

How is PsA diagnosed?

Diagnosing PsA starts with you.

No single exam can determine diagnosis. It is important to provide your doctor with details about the symptoms you are experiencing. Tell your doctor if your joints are stiff, sore, or if movement causes pain. Sharing details will help your doctor understand how you’re doing, while allowing them to provide you with the earliest possible diagnosis.

Your doctor may examine your skin for plaques as well as your joints, looking for signs of joint swelling, tenderness, and pain. They may check your fingernails. A blood test, X-ray, or MRI may be used to help pinpoint a source of pain or inflammation.

How is PsA treated?

There are a variety of treatments.

Some people use over-the-counter products, while others get one or more treatments prescribed by a doctor. These include:

  • Nonsteroidal anti-inflammatory drugs (NSAIDs) that can relieve pain and reduce inflammation (i.e., ibuprofen, aspirin).
  • Disease-modifying antirheumatic drugs (DMARDs) that can be used to slow the progression of psoriatic arthritis.
  • Immunosuppressants reduce the activity of the immune system, which causes chronic inflammation that is associated with psoriatic arthritis.
  • Biologics, like SKYRIZI, that target key parts of the immune system that are linked to causing inflammation.
Talk to your doctor about your PsA treatment journey, and ask if SKYRIZI may be right for you.
