Psoriatic arthritis without psoriasis

Psoriatic arthritis is diagnosed from the whole pattern rather than from a skin finding alone. Some people develop joint inflammation before skin symptoms, while others have subtle psoriasis in areas such as the scalp, behind the ears, around the navel, or in skin folds. Nail pitting or separation can also provide useful clues. A family history of psoriasis, swollen fingers or toes, heel pain, back symptoms, or morning joint stiffness may be relevant. Joint pain and joint swelling have many possible causes, so their presence does not by itself confirm psoriatic arthritis.

Book a review if recurring pain, swelling, or stiffness affects daily tasks or continues after rest. Note which joints change, whether symptoms are worse in the morning, and whether they improve with movement. Check your nails and scalp for changes and mention any relatives with psoriasis or inflammatory arthritis. A clinician may examine your skin, nails, joints, and spine and may request tests to distinguish inflammatory arthritis from other conditions. Treatment can include a personalised exercise plan, physiotherapy, or medication; do not start or stop anti-inflammatory medication without checking its suitability.

Contact a clinician promptly for a newly swollen joint, rapidly worsening stiffness, or pain that is limiting walking or hand use. Seek urgent care for a hot, very swollen joint with fever, sudden loss of strength or sensation, or a painful red eye with light sensitivity or blurred vision. Those features need timely assessment because they may signal a problem requiring treatment beyond routine symptom management.

Ask: What findings would support or argue against psoriatic arthritis? Should my nails, scalp, and other skin areas be examined? Which tests or scans could clarify the cause? How can I protect painful joints while staying active? When should I return if swelling or stiffness changes?
