Overview

Psoriatic arthritis (PsA) is a chronic autoimmune condition, meaning your immune system mistakenly attacks healthy tissue, that occurs in people with psoriasis, a skin disease marked by red, scaly patches. It causes inflammation in your joints and the places where tendons and ligaments attach to bone, leading to pain, stiffness, and swelling. While there is no cure for PsA, modern treatments can effectively control symptoms, prevent joint damage, and help you live an active, full life.

Signs & Symptoms

Symptoms of psoriatic arthritis vary widely from person to person, and may develop slowly or come on suddenly. Common signs include:

Joint pain, swelling, and warmth, often in the fingers, toes, knees, ankles, or lower back
Stiffness, especially first thing in the morning or after resting for long periods
Skin changes from psoriasis, including red, scaly patches, often on the elbows, knees, scalp, or lower back
Nail changes, such as pitting (small dents), thickening, or separation from the nail bed
Swelling of entire fingers or toes, sometimes called 'sausage digits'
Fatigue and reduced range of motion in affected joints
Eye inflammation (uveitis), which can cause redness, pain, and light sensitivity

Causes & Risk Factors

Psoriatic arthritis happens when your immune system mistakenly attacks healthy joints and skin tissue, causing inflammation. The exact cause is not fully understood, but several factors increase your risk:

Having psoriasis: 30% of people with psoriasis will develop PsA, usually within 7 to 10 years of a psoriasis diagnosis, though it can start before skin symptoms appear
Family history: Genetics play a role, and you are more likely to develop PsA if a close relative has psoriasis or PsA
Age: PsA most often develops between ages 30 and 50, but it can occur at any age, including in children
Environmental triggers: Infections (such as strep throat), stress, injury to a joint, or certain medications may trigger the onset of PsA in people with a genetic predisposition

Diagnosis

There is no single test for psoriatic arthritis, so your healthcare provider will use a combination of exams, medical history, and tests to confirm a diagnosis. They may refer you to a rheumatologist, a doctor who specializes in autoimmune joint conditions. Common diagnostic steps include:

Physical exam to check for swollen joints, skin and nail changes, and patterns of tenderness
Blood tests to rule out other types of arthritis (such as rheumatoid arthritis) and check for inflammation markers
Imaging tests, including X-rays, ultrasound, or MRI, to look for joint damage and inflammation
Review of your personal and family medical history, including any history of psoriasis

Early Diagnosis Is Critical

Delaying diagnosis and treatment can lead to permanent joint damage and long-term disability. If you have psoriasis and notice joint pain, swelling, or stiffness, schedule an appointment with your provider as soon as possible.

Treatment & Management

Treatment for psoriatic arthritis is tailored to your specific symptoms, severity, and overall health, with the goal of reducing inflammation, relieving pain, preventing joint damage, and managing skin symptoms. Most people use a combination of therapies:

Treatment Type	Purpose	Common Examples
Nonsteroidal anti-inflammatory drugs (NSAIDs)	Relieve mild pain and reduce inflammation	Ibuprofen, naproxen
Disease-modifying antirheumatic drugs (DMARDs)	Slow disease progression and prevent joint damage	Methotrexate, sulfasalazine, leflunomide
Biologic medications	Target specific parts of the immune system to reduce inflammation, often used for moderate to severe PsA	TNF inhibitors (adalimumab, etanercept), IL-17 inhibitors (secukinumab, ixekizumab), IL-12/23 inhibitors (ustekinumab)
Targeted synthetic DMARDs	Oral medications that target specific immune pathways, used when other treatments are not effective	Tofacitinib, upadacitinib
Corticosteroids	Reduce severe inflammation quickly, usually used short-term for flare-ups	Prednisone, joint injections of cortisone
Physical and occupational therapy	Improve joint function, strength, and range of motion	Custom exercise plans, joint protection techniques
Skin treatments	Manage psoriasis symptoms, which can improve overall PsA control	Topical corticosteroids, vitamin D analogues, phototherapy

Recovery & management timeline

0-30 days
Initial Symptom Onset
Track your joint pain, stiffness, and skin symptoms in a daily log. Schedule an appointment with your primary care provider or dermatologist to discuss your symptoms, and ask for a referral to a rheumatologist if you have a history of psoriasis.
1-90 days
Diagnosis & Treatment Start
Complete any recommended blood tests or imaging. Work with your rheumatologist to develop a personalized treatment plan, including any prescribed medications. Start gentle, low-impact exercise like walking or swimming to maintain joint mobility.
Ongoing
Long-Term Management
Attend regular follow-up appointments with your care team to monitor symptoms and adjust treatment as needed. Report any new or worsening symptoms to your provider right away, and continue consistent self-care habits.

Self-care steps

1Stay active with low-impact exercise

Regular movement like walking, swimming, cycling, or yoga helps keep joints flexible, strengthens muscles that support your joints, and reduces fatigue. Aim for 150 minutes of moderate activity per week, and avoid high-impact exercises that put stress on sore joints.

2Maintain a healthy weight

Excess weight puts extra stress on weight-bearing joints (knees, hips, back), which can worsen pain and inflammation. A balanced diet rich in fruits, vegetables, whole grains, and lean proteins can help you maintain a healthy weight and may reduce inflammation.

3Protect your joints during daily tasks

Use assistive devices (like jar openers, long-handled tools, or supportive shoes) to reduce strain on daily activities. Avoid repetitive motions that stress affected joints, and take regular breaks during tasks that require prolonged joint use.

4Manage stress and prioritize sleep

Stress can trigger PsA flare-ups, and poor sleep worsens pain and fatigue. Practice stress-reduction techniques like meditation, deep breathing, or journaling, and aim for 7-9 hours of sleep per night by sticking to a consistent bedtime routine.

5Avoid smoking and limit alcohol

Smoking is linked to more severe PsA symptoms and reduced effectiveness of some medications. Limiting alcohol can also reduce inflammation and lower the risk of medication side effects, especially if you take methotrexate.

When to seek medical help

Seek urgent medical care if you experience sudden, severe joint pain or swelling; redness, warmth, or tenderness in a joint that could signal an infection; vision changes, eye pain, or light sensitivity (signs of uveitis, a serious eye inflammation); or shortness of breath, chest pain, or coughing up blood, which can be rare but serious complications of PsA or its treatments.

Frequently asked questions

Is psoriatic arthritis the same as rheumatoid arthritis?

No, psoriatic arthritis and rheumatoid arthritis (RA) are both autoimmune inflammatory arthritis conditions, but they have different causes, symptoms, and treatments. PsA is linked to psoriasis, often affects different joints (like the fingers and toes, causing 'sausage digits'), and may cause skin and nail changes that RA does not. Blood tests for RA (like rheumatoid factor) are usually negative in PsA.

Can psoriatic arthritis go into remission?

Yes, many people with psoriatic arthritis achieve remission, meaning symptoms are minimal or absent, and joint damage is prevented. Remission is most often achieved with consistent, long-term use of targeted medications like biologics, combined with healthy lifestyle habits.

Will my psoriasis get better if my PsA is treated?

Some PsA treatments, especially biologics, improve both joint inflammation and psoriasis skin symptoms. However, you may also need separate skin treatments from a dermatologist to fully manage your psoriasis. Let your care team know about both your joint and skin symptoms so they can adjust your treatment plan as needed.

Can I still exercise if I have psoriatic arthritis?

Absolutely! Regular, low-impact exercise is one of the best things you can do to manage PsA. It reduces joint stiffness, strengthens supporting muscles, improves mood, and lowers fatigue. If you’re new to exercise, start with short, gentle sessions like walking or swimming, and talk to a physical therapist to create a plan that works for your joints.
