One swollen hand: what it may mean

A fall, twist, overuse, insect bite, or tight item can cause local swelling. Pain near the wrist after a fall may need assessment for a fracture, including a distal radius fracture. Warmth, redness, tenderness, or discharge can occur with infection and needs medical review. Morning stiffness and swelling in several finger or wrist joints can occur with rheumatoid arthritis. Swelling without an obvious trigger can also reflect fluid or blood-flow changes, so the hand's appearance and the speed of onset are useful clues.

Take off rings, bracelets, and tight sleeves. Rest the hand above heart level when possible and avoid heavy gripping. Gentle finger opening and closing may help if it is comfortable, but stop if pain rises. A cool pack wrapped in fabric can be used briefly after a minor injury. Do not puncture a blister or apply a tight bandage to an unexplained swelling. Photographing the hand and noting onset can help a clinician compare changes.

Seek urgent care if the hand becomes blue, pale, cold, numb, severely painful, rapidly more swollen, or difficult to move. Get prompt medical advice for fever, spreading redness, pus, or a wound. After trauma, marked tenderness, deformity, or inability to use the wrist or fingers should be assessed. Arrange review if swelling does not settle or keeps returning.

Could this be a soft-tissue injury, joint inflammation, infection, or a circulation issue? Do I need imaging or blood tests? What hand movements and pain relief options are suitable for me?
