What is psoriatic spondylitis?
Psoriatic spondylitis is a form of psoriatic arthritis.
Psoriatic arthritis refers to a group of inflammatory joint problems related to psoriasis. However, not everyone who has psoriatic arthritis has psoriasis.
Psoriatic spondylitis occurs when the body’s immune system attacks its own tissue, which leads to inflammation and often painful symptoms.
