Leading experts have joined together for the first time to call for better screening of psoriatic arthritis to help millions of people worldwide suffering from the condition.
Psoriatic arthritis (PsA) causes painful joint inflammation and can cause irreversible joint damage if left untreated.
PsA tends to affect people with the skin condition psoriasis, which causes a red, scaly rash, and affects approximately two per cent of people in the UK.
Around one in five go on to develop PsA – usually within ten years of the initial skin problem being diagnosed.
