What should you know about the most common joint involved in psoriatic arthritis?

Psoriatic arthritis is an inflammatory condition with patterns that vary between people. The hands and feet may become painful, swollen, and stiff, sometimes with swelling through the length of a finger or toe rather than at one joint alone. Knees, ankles, wrists, the lower back, or areas where tendons attach to bone can also be involved. Symptoms may affect one side, both sides, or move between different areas.

Joint swelling and morning joint stiffness are useful details to record, but they do not by themselves confirm Psoriatic Arthritis. Skin or nail psoriasis, family history, and the overall examination can help a clinician interpret the pattern.

Keep a simple record of which joints hurt or swell, how long stiffness lasts after waking, and whether movement improves or worsens symptoms. Protect an acutely swollen joint from heavy loading without keeping it completely still for long periods. A clinician may discuss Anti-Inflammatory Medication and refer you for Physiotherapy to preserve movement, strength, and hand or foot function. Treatment is tailored to the joints involved and to skin, nail, eye, or other symptoms.

Book a clinical review when pain, swelling, or stiffness persists, returns, or limits work, sleep, walking, or hand use. Seek urgent assessment for a hot, very swollen joint with fever or feeling acutely unwell, or for sudden painful eye redness or vision change. Rapidly increasing swelling deserves timely advice even if the pain is moderate.

Which joints or tendon areas appear inflamed? Could the whole finger or toe swelling fit this condition? What should I record at home? Would Anti-Inflammatory Medication or Physiotherapy suit my symptoms? How will we monitor joint function and treatment response?
