Skin, Hair and Nails

The risk of psoriatic arthritis (PsA) is much higher in people with psoriasis (PsO) than in those without the chronic skin disease. Fewer than 1% of Americans overall will develop joint pain and swelling from psoriatic arthritis. But in those with psoriasis, around 1 in 3 will get psoriatic arthritis, sometimes many years later. Both psoriasis and psoriatic arthritis stem from a combination of genetic and environmental factors. Your genes put you at risk for these conditions, but then something in your lifestyle triggers these diseases so they start exhibiting symptoms.
