What should you know about nail changes in psoriatic arthritis?

Psoriatic arthritis may affect the nail-forming tissues. Changes can include small pits, ridges, thickening, separation from the nail bed, crumbling, or altered colour. One nail or several nails may be involved, and the appearance can change as inflammation varies.

Nail findings alone do not establish the diagnosis. Fungal infection, injury, eczema, and other nail disorders can look similar. A clinician considers the nails together with skin findings, joint symptoms, tendon pain, and the examination.

Record when the change began and photograph it in consistent lighting. Mention tenderness, separation, skin plaques, finger swelling, back pain, or stiffness after waking. Keep nails trimmed, avoid biting or picking, and protect them from repeated trauma and harsh chemicals.

Arrange an assessment if changes persist, spread, or occur with joint symptoms. Treatment may involve a coordinated plan for inflammation, such as Anti-Inflammatory Medication, and movement support through Physiotherapy.

Seek prompt care for a painful, hot, rapidly swollen finger or toe, pus, spreading redness, fever, or sudden inability to move a joint. New persistent Joint Pain, Joint Swelling, or Morning Joint Stiffness also warrants assessment because early recognition can guide management.

Could this nail change have another cause, such as infection or injury? Do my nail findings fit with Psoriatic Arthritis? Should the nail be tested? Which treatment is aimed at the nails, and what joint symptoms should I track?
