Description

Psoriasis is a chronic, autoimmune disease that causes rapid buildup of skin cells, resulting in thick, scaly patches called plaques that can be itchy, painful, and affect the scalp, elbows, knees, and lower back. It has a genetic component and is triggered by factors like infections, stress, or certain medications. While there is no cure, treatments including topical creams, phototherapy, and systemic medications can help control symptoms and reduce flare-ups. Some people also develop psoriatic arthritis, which causes joint pain and swelling.
