What does psoriatic arthritis cause?
ANSWER
Psoriatic arthritis causes inflammation in your joints. It happens because your immune system is overactive. It affects mostly people who have psoriasis, a skin disease that's also related to the immune system. Sometimes doctors misdiagnose it as gout, rheumatoid arthritis, or osteoarthritis.
