What is psoriatic arthritis and how is it diagnosed?

Psoriatic arthritis is an immune-mediated arthritis that often occurs in people with psoriasis but can appear before or after skin symptoms. Common features include asymmetric joint pain, dactylitis (sausage-like swelling of a finger or toe), enthesitis (inflammation at tendon or ligament insertions), and nail changes. Diagnosis usually combines a clinical exam, patient history, blood tests to exclude other conditions, and imaging such as X-rays or ultrasound to assess joint and soft-tissue inflammation. Rheumatologists commonly lead diagnosis and management.

What medical treatments are available?

Medical therapy is the foundation of treatment and varies by disease severity. For mild symptoms, nonsteroidal anti-inflammatory drugs (NSAIDs) can relieve pain and stiffness. Conventional disease-modifying antirheumatic drugs (DMARDs) such as methotrexate or sulfasalazine are often used to slow disease progression. Targeted biologic therapies (for example, TNF inhibitors or interleukin inhibitors) and small-molecule agents (JAK inhibitors) are options when conventional agents are inadequate. Choice of medication depends on joint and skin involvement, coexisting conditions, monitoring needs, and patient preferences. All prescription treatments require medical supervision and regular monitoring for side effects.

How can physical therapy and exercise help?

Physical therapy and tailored exercise programs support mobility, joint stability, and muscle strength while reducing pain and stiffness. A physiotherapist or occupational therapist can recommend range-of-motion exercises, low-impact aerobics (swimming, cycling), strengthening routines, and joint-protection techniques for daily activities. Assistive devices or splints may improve function during flare-ups. Consistent, gentle exercise is generally recommended over long periods rather than short bursts of high intensity, and programs should be adapted during active inflammation.

What lifestyle changes and self-care support treatment?

Lifestyle measures complement medical care and may improve symptoms and overall health. Maintaining a healthy weight reduces stress on joints. Smoking cessation and limiting excessive alcohol are linked to better treatment response. Skin care for psoriasis, stress management, good sleep, and a balanced diet rich in fruits, vegetables, and omega-3 sources can support general well-being; evidence for specific “anti-inflammatory” diets is limited, so dietary changes should be realistic and sustainable. Patients should coordinate self-care with their clinical team to avoid interactions with medications or therapies.

Who should manage treatment and how are decisions made?

Management is typically multidisciplinary, involving a rheumatologist and, when skin disease is significant, a dermatologist. Primary care physicians, physiotherapists, occupational therapists, and sometimes orthopedic surgeons or pain specialists may also be involved. Treatment decisions follow a shared decision-making model that considers disease activity, comorbidities, treatment risks, and patient goals. Regular monitoring—clinical assessments, blood tests, and periodic imaging—helps guide medication adjustments and detect complications early. If you need referrals, look for local services that offer coordinated rheumatology and dermatology care.

In summary, psoriatic arthritis treatment combines medical therapies to control inflammation, rehabilitation to preserve function, and lifestyle strategies to support overall health. Because the condition varies widely between individuals, personalized care plans and ongoing monitoring are important to reduce symptoms, prevent joint damage, and maintain quality of life.
