Psoriasis can appear suddenly or slowly. Many times, it goes away and then comes back again and again.
• Irritated, red, flaky patches of skin
• Most often seen on the elbows, knees, and middle of the body
• Red patches may appear anywhere on the body, including the scalp
The skin may be:
• Dry and covered with silver, flaky skin (scales)
• Pink-red in color (like the color of salmon)
• Raised and thick
Other symptoms may include:
• Genital lesions in males
• Joint pain or aching
• Nail changes, including thick nails, yellow-brown nails, dents in the nail, and nail lifts off from the skin underneath
• Severe dandruff on the scalp
Psoriasis may affect any or all parts of the skin. There are five main types of psoriasis:
Erythrodermic the skin redness is very intense and covers a large area.
Guttate small, pink-red spots appear on the skin.
Inverse skin redness and irritation occurs in the armpits, groin, and in between overlapping skin.
Plaque thick, red patches of skin are covered by flaky, silver-white scales. This is the most common type of psoriasis.
Pustular white blisters are surrounded by red, irritated skin.
