Psoriatic Arthritis

What is Ankylosing Spondylitis?

Psoriatic arthritis is a type of arthritis that can happen in people who have psoriasis, a skin condition that causes red, scaly patches. In this condition, the immune system attacks both the skin and the joints, leading to pain, swelling, and stiffness.

It can affect any joint, including the fingers, toes, knees, spine, and even the places where tendons attach to bones (like the back of the heel).

How can I recognize it?

You might notice:

• Joint pain and swelling, often in fingers, toes, knees, or spine
• Stiffness in the morning lasting for more than 30 minutes
• Swollen fingers or toes that look like sausages (called “dactylitis”)
• Pain at the heels or soles of the feet
• Red, scaly patches on the skin, often on elbows, knees, or scalp
• Changes in the nails, like pitting (tiny dents), thickening, or separation
• Pain in the lower back or buttocks associated with stiffness
