Understand

Psoriasis is a long-term immune-mediated inflammatory condition that speeds skin-cell turnover.

Dry, scaly, itchy or painful plaques often affect elbows, knees, scalp and nails.

Genetic and immune factors contribute; infection, stress, skin injury or medicines can trigger flares.

Skin and nail examination is often enough; joint symptoms should also be assessed.

Biopsy is rarely needed; some treatments require tests before and during use.

Flares and remissions vary; psoriatic arthritis and other associated health problems may occur.

Topical treatment, phototherapy or systemic medicines are selected by extent, impact and risks.

Seek advice for persistent or extensive plaques, or painful or swollen joints.

Widespread redness, extensive pustules, fever or feeling unwell may signal severe disease and needs urgent help.

A procedure linked to a condition does not establish an indication for your individual situation.
