Up to 4 in 10 people with psoriasis develop psoriatic arthritis
Psoriasis usually appears first, sometimes years before the symptoms of psoriatic arthritis begin. However, psoriasis and psoriatic arthritis can start simultaneously or, more rarely, psoriatic arthritis can exist on its own or before skin symptoms.
People with psoriasis that affects the scalp or nails, or causes inflammation of the skin in the buttock area, may be at increased risk of developing psoriatic arthritis. Furthermore, the risk of developing psoriatic arthritis is at least twice as likely for people living with psoriasis in more than three affected sites.
If you have psoriasis, additional joint pain could be a sign that psoriatic arthritis has developed – but that’s not all there is to look out for.
