Psoriasis is a long-term skin condition that causes red, scaly patches, often on the elbows, knees, scalp and lower back. It is common, not contagious, and tends to flare and settle over time.
Common symptoms
- Red patches of skin covered with silvery-white scale
- Dry, cracked skin that may itch or bleed
- Thickened or pitted nails
- Scaly patches on the scalp
- Stiff or painful joints in some people (this should be assessed)
Common triggers
Flares can be linked to stress, skin injury, infections, certain medicines, smoking, alcohol and cold weather. Triggers differ from person to person.
Assessment and treatment
Psoriasis is usually diagnosed from the appearance of the skin. Treatment depends on the type, location and severity, and may include regular moisturising, creams and ointments, and treatments for the scalp. Some people need specialist treatment, and Dr Ratu will advise if a referral is appropriate.
Self-care
Many people find it helps to moisturise daily, avoid harsh soaps, manage stress and keep to a healthy weight. Avoid picking or scratching plaques.
When to seek help promptly
Seek medical advice if psoriasis spreads quickly over much of the body, becomes very red and painful, you develop joint pain or swelling, or the skin looks infected.
