What should you know about nail problems with psoriatic arthritis?

Psoriatic arthritis can involve the tissues that make and support a nail. Affected nails may become rough, fragile, discoloured, thickened, or partly detached. The surrounding skin may be scaly or sore, and a nearby finger or toe can become swollen or tender.

Nail appearance cannot identify the cause by itself. Fungal infection, an old injury, skin inflammation, and medication effects can look alike. The clinician will connect the nail pattern with joint symptoms, skin changes, family history, and examination findings.

Keep nails clean and trimmed, but do not cut into sore skin or pull away a loose section. Choose comfortable footwear for toenail changes, protect hands from prolonged water exposure, and avoid acrylic products if the nail is damaged or lifting. Note changes with dated photographs.

Tell a clinician about pain, drainage, new nail involvement, or stiffness after rest. Management may combine Anti-Inflammatory Medication with activity guidance and Physiotherapy when joint inflammation affects strength or function.

Arrange an appointment when nail changes persist, interfere with daily tasks, or appear with Joint Pain, Joint Swelling, or Morning Joint Stiffness. Get prompt medical help for spreading redness, pus, fever, severe digit swelling, or sudden difficulty using the finger or toe.

Could an infection or injury be contributing to this nail problem? Do the nail and joint findings suggest Psoriatic Arthritis? What treatment targets the nail process? How can I protect the nail at work, during exercise, or in shoes?
