If you have psoriasis, you should know about psoriatic arthritis (PsA). These related autoimmune diseases both cause itchy, red patches and inflammation on the skin. PsA also causes pain and swelling in your joints.
Researchers don't know why some people with psoriasis also develop PsA. They suspect it's a combination of genetic and environmental factors. Here's what you need to know about PsA.
Watch for symptoms
Be aware that symptoms often appear and disappear. Times when you experience increased symptoms and inflammation are called flare-ups, and they can last for days or months before easing. Watch for these symptoms of PsA:
• Painful, itchy spots or silvery white patches of dead skin on the knees and elbows.
• Pain, tenderness or swelling in the fingers, wrists, ankles or knees.
• Unexplained tiredness.
• Low-grade fever.
How it's diagnosed
There's no single screening for PsA, so your health care provider will consider a number of factors to diagnose the condition.
Here's what to expect:
• You'll be asked for your medical history. Be prepared to tell your doctor about your symptoms and any other family members who have autoimmune conditions.
• You'll be examined. Your provider will check for pain, tenderness, swelling or warmth. They'll also check for any mobility problems.
• You'll likely undergo tests. These may include x-rays and blood tests.
Left untreated, the inflammation caused by PsA can lead to other serious health problems, including heart damage, osteoporosis, vision problems, lung problems and metabolic syndrome.
Get the treatment you need
If you have PsA, prompt diagnosis and treatment can boost your quality of life. Every person is different, but a combination of over-the-counter and prescription medications is often used.
Luckily, you can feel better and minimize PsA flare-ups by making several lifestyle changes, such as:
• Swimming, walking, biking or doing another low-impact exercise regularly.
• Keeping skin moisturized with lotions containing aloe vera, jojoba or zinc.
• Eating an anti-inflammatory diet rich in fruits and vegetables and low in sugar, fat and salt.
• Managing stress with practices like meditation, yoga or tai chi.
