psoriatic

Psoriasis is a skin disease that causes itchy or sore patches of thick, red skin with silvery scales. You usually get them on your elbows, knees, scalp, back, face, palms and feet, but they can show up on other parts of your body.

Some people with psoriasis have psoriatic arthritis. It causes pain, stiffness, and swelling of the joints. It is often mild, but can sometimes be serious and affect many joints. The joint and skin problems don't always happen at the same time.

Your doctor will do a physical exam and imaging tests to diagnose psoriatic arthritis. There is no cure, but medicines can help control inflammation and pain. In rare cases, you might need surgery to repair or replace damaged joints.

Psoriasis is a skin disease that causes itchy or sore patches of thick, red skin with silvery scales. You usually get the patches on your elbows, knees, scalp, back, face, palms and feet, but they can show up on other parts of your body. Some people who have psoriasis also get a form of arthritis called psoriatic arthritis.

A problem with your immune system causes psoriasis. In a process called cell turnover, skin cells that grow deep in your skin rise to the surface. Normally, this takes a month. In psoriasis, it happens in just days because your cells rise too fast.

Psoriasis can be hard to diagnose because it can look like other skin diseases. Your doctor might need to look at a small skin sample under a microscope.

Psoriasis can last a long time, even a lifetime. Symptoms come and go. Things that make them worse include:

• Infections
• Stress
• Dry skin
• Certain medicines

Psoriasis usually occurs in adults. It sometimes runs in families. Treatments include creams, medicines, and light therapy.

If you feel pain and stiffness in your body or have trouble moving around, you might have arthritis. Any disorder that affects the joints is often called arthritis. Joints are places where two bones meet, such as your elbow or knee.

Most types of arthritis can cause joint pain and inflammation (swelling). Over time, a swollen joint can become severely damaged. Some kinds of arthritis can also cause problems in your organs, such as your eyes or skin. Treatment will depend on the type of arthritis you have.

Common types of arthritis include:

• Osteoarthritis is the most common type of arthritis. It's often related to aging or injury.
• Autoimmune arthritis happens when your body's immune system attacks healthy cells in your body by mistake. Rheumatoid arthritis is the most common form of this type of arthritis.
• Juvenile arthritis is a type of arthritis that happens in children.
• Infectious arthritis is an infection that has spread from another part of your body to the joint. Reactive arthritis is one type.
• Psoriatic arthritis affects people with psoriasis (itchy or sore scaly red and white skin patches).
• Gout is a painful type of arthritis that happens when too much uric acid builds up in your body. It often starts in the big toe. Other joints can also be affected.
• Ankylosing spondylitis is a type of arthritis of the spine that can cause stiffness and make it difficult to move and bend.

Pain, redness, warmth, and joint inflammation are common arthritis symptoms. You may not be able to move your joint as well as it should. Other symptoms could include fever, weight loss, breathing difficulties, or a rash.

Symptoms often get worse as you age. Some symptoms of arthritis may be signs of other illnesses.

A few things that might increase your chance of getting arthritis include:

• Family history. You may be more likely to get certain types of arthritis if a member of your family has the disorder.
• Age. The risk of getting many types of arthritis increases with age.
• Sex. Certain types of arthritis are more common in women, while other types are more common in men.

Other factors that might increase your risk of getting arthritis include having a previous joint injury, obesity, or lupus.

To find out if you have arthritis, your health care provider may:

• Ask you about your medical history, including your symptoms.
• Do a physical exam.
• Order blood tests or take x-rays.

Your provider may refer you to a rheumatologist (a doctor who specializes in arthritis care) for tests, diagnosis, and care.

Treatment depends on the type of arthritis you have. It may include medicine or surgery. Your provider will work with you to improve your symptoms and quality of life.

A few ways to help manage your symptoms include:

• Hot or cold packs
• Relaxation techniques
• Use of splints, braces, and/or assistive devices
