Psoriatic arthritis (PsA) is inflammatory arthritis that affects people with psoriasis, a skin condition that causes a red, scaly rash. Psoriatic arthritis usually affects the skin and joints, causing them to swell, stiffen, and hurt. If left untreated, inflammation can cause damage to joints and tissues over time.
Psoriatic arthritis has no known cure. Controlling inflammation in your affected joints to prevent joint pain and disability, as well as controlling skin involvement, are the main goals of treatment. Prescription pharmaceuticals known as disease-modifying antirheumatic drugs are one of the most prevalent therapies (DMARDs).
