Psoriatic arthritis
Between 10% and 20% of people with psoriasis develop psoriatic arthritis, which causes tenderness, pain and swelling in the joints and connective tissue with associated stiffness. It commonly affects the ends of the fingers and toes. In some people it affects the lower back, neck and knees. About 80% of those affected develop psoriatic arthritis after the onset of psoriasis, but in about 20% the arthritis occurs before the onset of psoriasis.
There is no single test for psoriatic arthritis. It is normally diagnosed using a combination of methods - looking at your medical history, physical examinations, blood tests, X-rays and MRI scans.
Psoriatic arthritis can be treated with anti-inflammatory or anti-rheumatic medicines.
Psychological complications
Due to the unpleasant effects psoriasis can have on physical appearance, feelings of low self-esteem and anxiety are common among people living with this condition. These feelings can then trigger depression, especially if the psoriasis worsens.
Your GP or dermatologist will understand that psoriasis has a psychological and emotional impact, so don't be afraid to discuss any concerns or anxieties you may have.
Many people living with psoriasis have found getting involved in support groups may help. Support groups can help increase your self-confidence and reduce any feelings of isolation, while offering practical advice about living with the condition.
