It’s important to learn as much as you can about your condition. That includes understanding your symptoms and how PsA affects your body. Knowing more can help you talk with your doctor about the treatment that’s right for you.
Normally, your immune system works to protect your body from foreign substances like bacteria, viruses, and germs. While the exact cause is unknown, when you have PsA, your immune system attacks healthy tissue and cells in your body. That’s why PsA is called an autoimmune disease.
PsA symptoms may include:
PsA is a chronic, or long-term, disease. If the pain, stiffness, swelling, and skin symptoms are not caught early, they can worsen over time. That’s why early diagnosis and treatment are important. While there is no cure, there are medicines that can help relieve these symptoms. This can help you perform everyday activities with less difficulty.
PsA affects up to 1% of the US population, including up to 30% of patients with psoriasis (but frequently undiagnosed).

PsA often appears between the ages of 30 and 55 years.
PsA is more common in Caucasians than African Americans or Asian Americans.
