Hand swollen and painful for no reason: what to know

Swelling can reflect irritation of tendons or joints, a minor injury you did not notice, fluid retention, or inflammatory arthritis. Pain with reduced movement, bruising, or tenderness after a knock raises concern for an injury such as a distal radius fracture. Rheumatoid arthritis can cause painful, puffy joints, often with stiffness in several fingers or both hands. Hand swelling is a symptom rather than a diagnosis, so its timing, location, and accompanying changes matter.

Remove rings, watches, and tight bands before swelling increases. Rest the hand from gripping and keep it raised when comfortable. A wrapped cool pack may ease discomfort for short periods; protect the skin and stop if numbness or colour change develops. Do not force stiff joints or massage an area that is hot, red, or sharply painful. Note when symptoms began, whether one hand or several joints are affected, and any recent activity, bite, illness, or new medicine.

Arrange prompt medical care for increasing pain, marked warmth or redness, fever, pus, a wound, or swelling that is not settling. Seek urgent help if the fingers become blue, pale, numb, cold, or difficult to move, or if the hand looks deformed after an injury. Sudden swelling with breathing difficulty or swelling of the lips or face is an emergency.

Ask which joints or tissues appear involved, whether an examination or imaging is needed, and which pain-relief options fit your health history. Also ask how long to monitor the swelling and which changes should bring you back sooner.
