Patients often experience persistent pain in affected joints, especially fingers, toes, knees, and wrists. Morning stiffness lasting over 30 minutes is typical, easing gradually with movement. The joint swelling may be asymmetric, affecting some joints more than others, which can distinguish PsA from other arthritis forms.

Real-world Scenario: A patient notices swelling in their toes, making their footwear uncomfortable. Over weeks, the pain worsens, prompting a visit to the doctor and eventual diagnosis of psoriatic arthritis.

Inflammation at the attachment points of tendons and ligaments, known as enthuses, is a common early sign. This often presents as heel pain or pain at the bottoms of the feet, causing difficulty walking or standing for extended periods.

Many patients with PsA also develop psoriasis on their skin. These patches are often dry, scaly, and sometimes itchy, appearing on elbows, scalp, or lower back. Nail changes such as pitting, ridging, or loosening are frequent signs and may be the first indication of psoriatic disease.

Complete swelling of fingers or toes, called dactylitis, gives a sausage-like appearance and indicates extensive inflammation. Recognizing this sign can be pivotal for diagnosis and understanding disease progression.

Fatigue, malaise, and occasional low-grade fever are common systemic signs accompanying psoriatic arthritis, emphasizing its inflammatory nature.
