Psoriatic arthritis: A Comprehensive Guide

Primary Symptoms

• Joint pain and swelling - Pain and swelling in one or more joints, often affecting hands, feet, knees, and spine

• Morning stiffness - Joints feel stiff and hard to move for 30 minutes or more after waking up

• Sausage-like fingers or toes - Entire digits become swollen and puffy, called dactylitis

• Nail changes - Nails develop pits, ridges, or separate from the nail bed

• Fatigue - Feeling unusually tired due to inflammation throughout the body

• Heel or foot pain - Pain where tendons attach to bones, especially at the heel or bottom of feet

When to Seek Care

You should contact a healthcare provider if you experience persistent joint pain and stiffness, especially if you have psoriasis. Early treatment is important to prevent joint damage. Watch for swelling that doesn't improve with rest, severe morning stiffness, or pain that interferes with daily activities.

When to Seek Immediate Care

Seek emergency care if you develop severe joint swelling, inability to move affected joints, or signs of infection like fever and red, warm joints.

Medical History & Physical Examination

Your doctor will ask about your symptoms, family history, and any skin problems you've experienced. They'll want to know when your symptoms started, which joints hurt, and how the pain affects your daily life. The physical exam includes checking your joints for swelling, tenderness, and range of motion.

Your doctor will also examine your skin and nails for signs of psoriasis. Sometimes nail changes are the only visible sign of psoriasis, so this examination is important. They may also check for tender spots where tendons attach to bones, which is common in psoriatic arthritis.

Diagnostic Testing

• Blood tests - May show inflammation and help assess for other conditions, including rheumatoid arthritis, but no blood test can confirm psoriatic arthritis or completely rule out rheumatoid arthritis

• X-rays - Can show joint damage and bone changes that may support a diagnosis of psoriatic arthritis, especially later in the disease

• MRI or CT scans - Provide detailed images of joints and surrounding tissues to detect early changes

• Ultrasound - Can detect inflammation in tendons and joints that might not show up on X-rays

Conservative Treatments

• Anti-inflammatory medications - NSAIDs like ibuprofen help reduce pain and swelling in mild cases

• Disease-modifying antirheumatic drugs (DMARDs) - Medications such as methotrexate may help control peripheral joint symptoms and inflammation; the choice depends on the parts of the body affected and disease severity

• Topical treatments - Creams and ointments help manage skin symptoms of psoriasis

• Physical therapy - Exercises and stretches help maintain joint flexibility and strengthen supporting muscles

• Lifestyle changes - Weight management, stress reduction, and smoking cessation can improve symptoms

Advanced Treatments

• Biological therapies - Target specific parts of the immune system and may be recommended based on disease severity, the areas affected, and response to previous treatment

• JAK inhibitors - Newer oral medications that block certain immune system pathways

• Corticosteroid injections - Direct injection into severely affected joints for short-term relief

• Phototherapy - UV light treatment helps manage skin symptoms in some people

For people experiencing tendinitis and tenosynovitis along with joint symptoms, targeted treatments may be needed to address inflammation in tendons and their surrounding tissues.

Daily Management Strategies

Start each day with gentle stretching to reduce morning stiffness. Apply heat to stiff joints and cold to swollen ones. Plan demanding activities for the time of day when your energy and stiffness are most manageable. Keep a symptom diary to identify triggers and patterns.

Protect your joints during daily activities by using assistive devices when needed. Choose shoes with good support and avoid high heels. Maintain good posture and take breaks during repetitive activities. Stress management through meditation, deep breathing, or counseling can help reduce symptom flares.

Some psoriatic arthritis medications require liver monitoring. Report unexplained abdominal pain or other new symptoms to your healthcare provider, and complete any recommended blood tests.

Exercise & Movement

Low-impact exercises like swimming, walking, and cycling are ideal for maintaining joint health. Water exercises are particularly beneficial because water supports your body weight while providing resistance. Yoga and tai chi can improve flexibility and reduce stress.

Avoid high-impact activities like running on hard surfaces or contact sports during flares. Listen to your body and modify activities as needed. Range-of-motion exercises help maintain joint flexibility. Strength training with light weights can support and protect joints.
