Psoriatic arthritis is a type of arthritis that affects people who also suffer with psoriasis. This is a long-term skin condition that causes painful dry, red, and flaky skin. According to the NHS, almost 1 in 3 people with psoriasis also have psoriatic arthritis, and usually develops years after psoriasis has been diagnosed.
Psoriatic arthritis has similar symptoms to other types of arthritis, such as stiff and swollen joints.
