Items Tagged With Psoriasis Symptoms

The classic symptoms of psoriasis are raised, red patches of skin topped with loose, silvery scales, usually on the knees or elbows.

There are several types of psoriasis. Symptoms for each type may vary in severity and appear in a wide array of combinations. In general, the major symptoms of psoriasis include:

• Bright red areas of raised patches (plaques) on the skin, often covered with loose, silvery scales. Plaques can occur anywhere, but commonly they occur on the knees, elbows, scalp, hands, feet, or lower back. Nearly 90% of people with psoriasis have plaque-type psoriasis.¹
• Tiny areas of bleeding when skin scales are picked or scraped off (Auspitz's sign).
• Mild scaling to thick, crusted plaques on the scalp.
• Itching, especially during sudden flare-ups or when the psoriasis patches are in body folds, such as under the breasts or the buttocks.
• Nail disorders. Nail disorders are common, especially in severe psoriasis. Nail symptoms include:
  • Tiny pits in the nails (not found with fungal nail infections).
  • Yellowish discoloration of the toenails and possibly the fingernails.
  • Separation of the end of the nail from the nail bed.
  • Less often, a buildup of skin debris under the nails.

Other symptoms of psoriasis may include:

• Symmetrical plaques on the same areas on both sides of the body (for example, both knees or both elbows).
• Flare-ups of many raindrop-shaped patches. Called guttate psoriasis, this condition often follows a strep infection and is the second most common type of psoriasis. It affects less than 10% of those with psoriasis.¹
• Joint swelling, tenderness, and pain (psoriatic arthritis).These symptoms may occur in up to 39% of people with psoriasis.²

Koebner's phenomenon can occur when a person with psoriasis has an injury (such as a cut, burn, or excess sun exposure) to an area of the skin that is not affected by psoriasis. Psoriasis patches then appear on the injured skin or any other part of the skin from several days to about 2 weeks after the injury. Because this response is common, it is important for people who have psoriasis to avoid irritating or injuring their skin.

Several other skin conditions have symptoms similar to psoriasis. Some medication reactions can cause symptoms (such as reddened skin) similar to psoriasis. Talk to your doctor about any medications you are taking.

What is psoriasis?

Psoriasis (say "suh-RY-uh-sus") is a long-term (chronic) skin problem that causes skin cells to grow too quickly, resulting in thick, white, silvery, or red patches of skin. Normally, skin cells grow gradually and flake off about every 4 weeks. New skin cells grow to replace the outer layers of the skin as they shed. But in psoriasis, new skin cells move rapidly to the surface of the skin in days rather than weeks. They build up and form thick patches called plaques (say "plax").

The patches range in size from small to large. They most often appear on the knees, elbows, scalp, hands, feet, or lower back. Psoriasis is most common in adults, but children and teens can get it too.

Having psoriasis can be embarrassing, and many people, especially teens, avoid swimming and other situations where patches can show. But there are many types of treatment that can help keep psoriasis under control.

What causes psoriasis?

Experts believe that psoriasis occurs when the immune system overreacts, causing inflammation and flaking of skin.

In some cases, psoriasis runs in families. Researchers are studying large families affected by psoriasis to find out how it is passed from parents to their children and what might trigger the condition.

People with psoriasis often notice times when their skin gets worse. Things that can cause these flare-ups include a cold and dry climate, infections, stress, and dry skin. Also, certain medicines, such as nonsteroidal anti-inflammatory drugs (NSAIDs) and medicines used to treat high blood pressure or depression, may trigger an outbreak or make your psoriasis worse.

Smoking, especially in women, makes you more likely to get psoriasis and can make it worse if you already have it.

Psoriasis is not contagious. It cannot be passed from person to person.

What are the symptoms?

Symptoms of psoriasis appear in different ways. Psoriasis can be mild, with small areas of rash. When psoriasis is moderate or severe, the skin gets inflamed with raised red areas topped with loose, silvery, scaling skin. If psoriasis is severe, the skin becomes itchy and tender, and the large skin patches may be uncomfortable and embarrassing. The patches can join together and cover large areas of skin, such as the entire back.

In some people, psoriasis causes joints to become swollen, tender, and painful. This is called psoriatic arthritis (say "sor-ee-AT-ik ar-THRY-tus"). This arthritis can also affect the fingernails and toenails, causing the nails to pit, change color, and separate from the nail bed. Dead skin may build up under the nails.

Symptoms often disappear (go into remission), even without treatment, and then return (flare up).

How is psoriasis diagnosed?

A doctor can usually diagnose psoriasis by looking at the patches on your skin, scalp, or nails. Sometimes a skin KOH test is used to rule out a fungal infection, but otherwise, special tests are usually not needed.
