chronic inflammatory condition causing joint pain in psoriasis patients
Psoriatic Arthritis (PsA) is a chronic inflammatory condition that affects some people who have psoriasis, a skin disease characterized by red, scaly patches. PsA causes joint pain, stiffness, and swelling, and can lead to joint damage if not treated. It is an autoimmune disorder, meaning the body's immune system mistakenly attacks healthy tissue, and it can affect any joint in the body, including the spine.
