Presentations of Psoriatic Arthritis
Psoriatic arthritis (PsA) causes swelling, pain and stiffness in your joints and in areas where your tendons and ligaments connect to bone.
Just like psoriasis, PsA can range from mild to severe. Mild PsA is sometimes referred to as oligoarticular, meaning it affects four or fewer joints in the body. More severe PsA is often called polyarticular, meaning it affects five or more joints. But regardless of the severity, psoriatic arthritis can have a profound impact on pain, the ability to do daily tasks and move comfortably.
PsA can involve the peripheral joints (found in your arms and legs, including the elbows, wrists, hands and feet) or less commonly, the axial skeleton (spine, hips and shoulders).
Spondylitis is inflammation of the spinal column which affects 7 to 32 percent of people living with psoriatic arthritis. It is common in people living with psoriatic arthritis and can occur with other forms of PsA at the same time. Symptoms include inflammation with stiffness of the neck, lower back and sacroiliac joints. Spinal arthritis makes joint motion in these areas painful and difficult.
