What is the connection between enthesitis and arthritis?

ANSWER

Some kinds of arthritis are autoimmune disorders. This means your body's immune system makes chemicals that attack and damage your own tissues. This can cause enthesitis. It's a common symptom of two kinds of autoimmune arthritis -- psoriatic arthritis and ankylosing spondylitis. Psoriatic arthritis, which is common in people with the skin condition psoriasis, can affect your entire body. Ankylosing spondylitis mainly affects your spine.
