Psoriatic arthritis (PsA) is a chronic condition that can affect the joints and entheses, which are spots where ligaments and tendons attach to bones. It can cause pain, swelling, stiffness, and other symptoms.
Many people with PsA also have psoriasis, which can affect the skin and nails.
Some people with PsA also develop inflammation in other parts of the body, such as the eyes or colon.
New or worse symptoms of PsA may develop over time. The condition does not progress in the same way for everyone. Certain symptoms may affect some people but not others. Symptoms may develop along different timelines.
Treating PsA helps manage symptoms, reduce inflammation, and limit its progression.
A person can let their doctor know if they develop new or worse symptoms in or around their joints, skin, nails, or other body parts. Their doctor may order follow-up tests and recommend changes to their treatment.
