Psoriatic Arthritis is a chronic inflammatory condition that affects some people with psoriasis, a skin disorder characterized by red, scaly patches. This type of arthritis can cause pain, stiffness, and swelling in the joints, which may lead to reduced mobility and discomfort. It can affect any joint in the body, including fingers, toes, and the spine. The exact cause of Psoriatic Arthritis is not fully understood, but it is believed to involve a combination of genetic and environmental factors. Symptoms can vary widely among individuals, and early diagnosis and treatment are important to manage the condition effectively and prevent joint damage.
