Psoriatic arthritis is a type of inflammatory arthritis that occurs in people with psoriasis, a skin condition characterized by red, scaly patches on the skin.
Psoriatic arthritis can affect any joint in the body & typically causes joint pain, stiffness, & swelling.
The exact cause of psoriatic arthritis is not known, but it is believed to be related to an autoimmune reaction in which the body's immune system mistakenly attacks healthy tissue, including joints & skin.
Symptoms of psoriatic arthritis can vary from mild to severe & can come & go over time.
Common symptoms include joint pain, swelling, & stiffness, especially in the fingers & toes.
Other symptoms may include fatigue, nail changes, eye problems, & skin patches.
Treatment for psoriatic arthritis typically involves a combination of medications, such as nonsteroidal anti-inflammatory drugs (NSAIDs), disease-modifying antirheumatic drugs (DMARDs), & biologic agents.
