Psoriatic Arthritis
Understand the symptoms, medical care, exercise options and practical strategies that may help you stay active with psoriatic arthritis.
Psoriatic arthritis, often shortened to PsA, commonly develops in people with psoriasis. However, joint symptoms can occasionally appear before obvious skin changes. Symptoms and disease activity vary considerably between people, so early medical assessment matters.
A GP or rheumatologist manages diagnosis and medical treatment. Meanwhile, a physiotherapist can help you adapt activity, build an appropriate exercise program and manage the physical effects of pain, stiffness, weakness and fatigue.
What is psoriatic arthritis?
Psoriatic arthritis is an immune-mediated inflammatory arthritis associated with psoriasis. Inflammation may affect the lining of joints, tendon and ligament attachment sites, fingers, toes and parts of the spine.
Persistent inflammation can gradually damage joints or reduce function. Therefore, the central treatment goal is to control disease activity early and maintain it at a low level. Your medical team may describe this as a treat-to-target approach.
PsA belongs to a broader group of inflammatory conditions called spondyloarthritis. You can explore related conditions through our arthritis and rheumatology conditions section.
Inflammatory
Symptoms may include swelling, heat and prolonged stiffness rather than pain from physical load alone.
Variable
Different joints and tissues may become involved, and symptoms can fluctuate between quieter periods and flare-ups.
Manageable
Medical care, exercise, education and activity planning can help many people maintain useful function and participation.
What are the symptoms of psoriatic arthritis?
PsA does not look the same in everyone. Some people mainly notice symptoms in their hands or feet. Others experience pain around tendon attachments or inflammatory stiffness through the spine and pelvis.
Painful or swollen joints
One or several joints may become sore, warm, swollen or difficult to move. Morning stiffness may last longer than ordinary stiffness after rest.
Swollen fingers or toes
A whole finger or toe may swell. Clinicians call this dactylitis, or sometimes a “sausage digit”.
Tendon attachment pain
Inflammation where tendons or ligaments attach to bone is called enthesitis. The heel, Achilles tendon and sole of the foot are common sites.
Back or buttock stiffness
Inflammation around the spine or sacroiliac joints may cause prolonged morning stiffness, alternating buttock pain or symptoms that improve with movement.
Skin and nail changes
Psoriasis plaques, nail pitting, nail thickening or separation of the nail from its bed can occur alongside joint symptoms.
Fatigue
Inflammation, pain, disrupted sleep and the effort of managing a long-term condition may reduce energy and exercise tolerance.
Other conditions can cause similar symptoms. Joint pain by itself does not confirm psoriatic arthritis, and an online symptom list cannot replace a medical assessment.
How is psoriatic arthritis diagnosed?
No single blood test confirms PsA. Your GP or rheumatologist considers the overall pattern of symptoms, skin and nail changes, joint examination, family history and other possible causes.
Assessment may include blood tests such as C-reactive protein or erythrocyte sedimentation rate. These tests can provide information about inflammation, although normal results do not automatically exclude PsA. X-rays, ultrasound or MRI may also help assess particular joints, tendon attachments or spinal areas.
-
Describe the complete symptom pattern
Tell your clinician about joint swelling, morning stiffness, heel pain, back symptoms, fatigue, psoriasis and nail changes.
-
Identify when symptoms began
Record whether symptoms appeared gradually or suddenly, which areas became involved and whether they fluctuate.
-
Discuss psoriasis and family history
Mild or hidden psoriasis can matter. Mention scalp, skin-fold or nail symptoms and any family history of psoriasis or inflammatory arthritis.
-
Complete the recommended investigations
Your doctor will select blood tests or imaging according to your presentation rather than relying on one routine test.
When should you seek medical care?
How is psoriatic arthritis treated?
Treatment usually combines medication, education, physical activity and management of related health factors. The exact plan depends on whether PsA affects peripheral joints, tendon attachments, the spine, skin, nails or several areas.
A rheumatologist may consider anti-inflammatory medicines, conventional disease-modifying antirheumatic drugs, biologic medicines or targeted synthetic therapies. Medication decisions require individual medical assessment, monitoring and discussion of potential benefits and risks.
Modern recommendations support adjusting treatment according to disease activity and the clinical areas involved. Some people reach remission or low disease activity, although this does not necessarily mean the condition has permanently disappeared.
Medication questions should be directed to your GP, rheumatologist or pharmacist. Do not stop prescribed medication because symptoms improve without first discussing the change with your treating clinician.
How may physiotherapy help?
Rheumatology physiotherapy does not replace medication that controls inflammatory disease. Instead, it addresses movement, strength, fitness and activity problems that can develop alongside PsA.
Your physiotherapist may help you:
- maintain or improve comfortable joint movement;
- build strength around affected joints;
- modify exercise during flare-ups;
- improve balance, mobility and physical confidence;
- manage tendon-loading problems such as heel or Achilles pain;
- plan work, household, recreational or sporting loads;
- select temporary joint-support or pacing strategies; and
- return gradually to valued activities after a period of reduced function.
Treatment should match your current disease activity and physical capacity. Forceful treatment over a hot, acutely inflamed joint is unlikely to be appropriate. Hands-on care may sometimes reduce surrounding muscle discomfort, but it does not control the underlying immune process.
What exercise is suitable for psoriatic arthritis?
Regular physical activity can support strength, mobility, cardiovascular health, mood and participation. However, the correct starting point varies with your symptoms, fitness, joint involvement and medical health.
Aerobic exercise
Walking, cycling, swimming or another rhythmic activity can build cardiovascular fitness. Lower-impact options may feel more comfortable when feet, knees or hips are irritated.
Strength exercise
Progressive resistance exercise can improve muscular support and physical capacity when the load and recovery period suit your current condition.
Mobility exercise
Gentle movement can help maintain useful range and reduce the effects of prolonged inactivity. Avoid repeatedly forcing an acutely swollen joint.
Water-based exercise
Hydrotherapy can provide a lower-impact environment for mobility, strengthening and general conditioning.
Begin below your current tolerance, monitor the response later that day and the following morning, and progress one variable at a time. A small increase in effort may be acceptable, but a marked and sustained flare in joint swelling, heat or pain indicates that the dose may need adjustment.
Activities such as Pilates or yoga may suit some people. Neither option is automatically appropriate for every joint or every flare. Modify positions and loading where required.
What can you do during a flare-up?
A flare is a period when symptoms or disease activity increase. Your medical team should help you develop an individual plan, particularly if flares are frequent, severe or associated with increasing swelling.
-
Check for warning signs
Seek medical advice for rapidly increasing swelling, marked heat, fever, eye symptoms or a major unexplained change.
-
Reduce irritating loads
Temporarily shorten, lighten or replace activities that repeatedly aggravate the affected area.
-
Keep moving comfortably
Use gentle movement and light activity where tolerated rather than assuming complete rest is always best.
-
Use your agreed symptom strategies
Follow medical advice. Heat may feel helpful for general stiffness, while a wrapped cold pack may feel more comfortable over a hot or swollen area.
-
Build back gradually
As symptoms settle, restore activity in manageable stages rather than immediately returning to your previous workload.
A short activity diary can help identify patterns involving workload, new exercise, sleep, stress and recovery. However, not every flare has an obvious or preventable trigger.
How can you reduce unnecessary joint stress?
- Change positions regularly: avoid staying in one posture for long periods when stiffness is building.
- Spread demanding tasks: divide heavy household, work or gardening jobs across the day or week.
- Use larger joints when practical: carry objects with both hands or use a bag rather than relying on sore finger joints.
- Choose suitable footwear: cushioning, fit and support may matter when heels, toes or forefeet are painful.
- Use supports selectively: a brace or orthosis may temporarily unload a painful joint, but unnecessary long-term use can restrict movement or strength.
- Resume activity progressively: rebuild capacity after a flare instead of alternating between complete rest and sudden high workloads.
A physiotherapist can help distinguish useful protection from excessive avoidance. Staying inactive for prolonged periods may contribute to weakness, reduced fitness and lower confidence with movement.
Can psoriatic arthritis go into remission?
Some people reach remission or low disease activity with appropriate treatment. In practical terms, this may mean minimal symptoms, better function and little evidence of active inflammation.
Remission does not guarantee that PsA has permanently resolved. Ongoing monitoring remains important because disease activity can change, and medication decisions must account for more than how a joint feels on a particular day.
Is surgery required?
Most people do not begin treatment with surgery. A specialist may consider an operation when a joint has advanced structural damage, severe persistent symptoms or major functional loss despite appropriate medical and rehabilitation care.
The procedure depends on the joint and the problem. Options may include joint replacement or another reconstructive procedure. Rehabilitation before and after surgery can help prepare physical capacity and restore function.

Psoriatic arthritis FAQs
What are the early signs of psoriatic arthritis?
Early signs may include recurring joint pain or swelling, prolonged morning stiffness, heel pain, a swollen finger or toe, fatigue, nail changes or new back stiffness. Symptoms vary, so a medical assessment is needed for diagnosis.
Can physiotherapy help psoriatic arthritis?
Physiotherapy may help maintain movement, strength, fitness and daily function. It can also guide activity modification and exercise during quieter periods or flare-ups. Physiotherapy supports, but does not replace, medical treatment that controls inflammation.
What exercise is best for psoriatic arthritis?
A balanced program often includes aerobic exercise, progressive strengthening and comfortable mobility work. The best exercises depend on the joints involved, current disease activity, general health and physical goals.
Can psoriatic arthritis cause back or buttock pain?
Yes. Psoriatic arthritis can affect the spine and sacroiliac joints. This may cause prolonged back stiffness, alternating buttock pain or symptoms that improve after movement. Other conditions can cause similar pain, so assessment is important.
Can psoriatic arthritis go into remission?
Some people reach remission or low disease activity with appropriate treatment. Continued medical monitoring remains important because symptoms and inflammation can change over time.
When should I see a doctor about possible psoriatic arthritis?
Arrange a GP assessment for persistent joint swelling, prolonged morning stiffness, recurring heel pain, a swollen finger or toe, or new joint symptoms with psoriasis. Seek urgent care for a very hot swollen joint with fever or for a painful red eye with light sensitivity or vision change.
