What should you know about swelling in left hand only?

A recent fall, blow, overuse, or tight grip may irritate tissues around the hand and wrist. A distal radius fracture can cause swelling near the wrist and hand after a fall. Joint inflammation may affect several knuckles, with stiffness that is more noticeable after rest; rheumatoid arthritis is one possible condition. Redness, warmth, tenderness, or a wound raises concern for infection. Numbness, colour change, or a cold hand can signal pressure on nerves or reduced blood flow. The location, onset, pain, movement, and whether rings feel tight help a clinician narrow the cause.

Remove rings and watches before swelling increases. Rest the hand from lifting and repetitive gripping, keep it raised when comfortable, and use a wrapped cool pack for short periods if the swelling followed a minor injury. Do not place ice directly on skin or force a painful joint through movement. Note when it began, any injury or bite, and changes in sensation or colour. A clinician may examine the hand and wrist and decide whether imaging or other tests are needed.

Seek urgent medical care for a hand that is suddenly very painful, pale, blue, cold, markedly numb, or difficult to move. Get prompt assessment if swelling is rapidly increasing, the skin is hot and red, fever develops, or there is pus or a deep wound. Arrange an appointment when one-sided swelling persists, keeps returning, or follows an injury that limits normal use.

Ask what structures appear swollen, whether an X-ray is needed, and which movements or activities to avoid. Ask how to protect the hand while swelling settles and what changes should trigger faster review.
