What should you know about joints involved in psoriatic arthritis?

Psoriatic arthritis may affect a single joint or several, and the pattern can be uneven from one side to the other. Swelling of an entire finger or toe can occur, while pain may also develop where a tendon or ligament attaches to bone, such as at the heel. The lower back or neck may be involved when inflammation affects the spine. Joint pain, swelling, and morning stiffness can limit grip, walking, or turning the head. Skin or nail psoriasis may be present, but joint symptoms can also need assessment when skin changes are subtle. A clinician considers the examination, symptom pattern, family history, skin and nail findings, and sometimes imaging or blood tests.

Keep a record of which joints swell, how long morning stiffness lasts, and whether symptoms follow activity or rest. Gentle movement and pacing can help preserve function; avoid complete inactivity during a flare unless a clinician advises it. Physiotherapy can tailor mobility, strengthening, joint protection, and energy-conservation strategies. Anti-inflammatory medication may be considered after a clinician checks your health, other medicines, and risks. Treatment aims to control inflammation and protect movement, so review is worthwhile when symptoms are new, persistent, or changing.

Arrange a medical review for ongoing joint swelling, repeated episodes, prolonged morning stiffness, new back pain with marked stiffness, or difficulty using a hand or walking. Seek urgent advice for a hot, very painful joint with fever or feeling unwell, or for sudden loss of strength or sensation. New eye pain, light sensitivity, or blurred vision also needs prompt assessment because inflammatory conditions can affect more than joints.

Ask which joints or tendon attachments appear involved, whether the pattern fits psoriatic arthritis, and whether imaging or blood tests would help. Discuss a movement plan, flare plan, medication choices, and which symptoms need urgent review.
