Symptoms Plaque psoriasis commonly causes raised scaly patches on the scalp, elbows, knees or lower back. Other forms can affect skin folds, nails, palms, soles or most of the body. Psoriasis is not contagious.
Triggers and associated health issues Flares may follow infections, stress, smoking, skin injury or certain medicines. Some patients develop psoriatic arthritis with joint pain, swelling or morning stiffness. Psoriasis is also associated with higher rates of cardiovascular and metabolic conditions.
Treatment Treatment depends on severity and location. Options include moisturisers, topical corticosteroids, vitamin D-type creams, phototherapy, tablets or injectable biologic medicines. Treatment aims to control inflammation, reduce scaling and improve quality of life.
When to seek care Dermatology assessment is recommended for widespread disease, nail changes, genital or facial involvement, significant emotional effect or failure of topical treatment. Joint pain, swelling or stiffness should be reported early.
