Swollen right hand in an older adult: what to know

Older adults may develop swelling after a minor knock that was not noticed or remembered, particularly when bone and soft tissues are more fragile. A wrist or hand fracture can cause swelling, bruising, tenderness, and reduced movement; a distal radius fracture may follow a fall onto the hand. Osteoarthritis can make selected finger or thumb joints enlarge and stiffen, while rheumatoid arthritis commonly presents with swollen, stiff joints and may affect both sides. A hot, red, tender hand can indicate infection or another urgent inflammatory problem. Swelling can also be influenced by medicines or circulation, but swelling limited to one hand should not be dismissed as normal ageing.

Remove rings promptly and compare the right hand with the left for colour, temperature, movement, and sensation. Elevate the hand during rest and avoid carrying heavy objects or leaning on the wrist. If there was a recent bump and the skin is intact, a wrapped cool pack may ease discomfort for short periods. Do not force a stiff joint or use a tight homemade bandage. Keep a list of medicines and note the onset, pain pattern, redness, and any recent fall; this information is useful during an appointment.

Seek urgent care for sudden swelling with severe pain, deformity, numbness, weakness, a cold or blue hand, or inability to move the fingers. Fever, spreading redness, pus, or marked warmth also needs prompt attention. Arrange a clinical assessment after any fall if tenderness or loss of function remains, even without obvious bruising. Persistent, recurrent, or unexplained swelling should be reviewed so the cause and appropriate treatment can be identified.

Could an unnoticed injury explain this swelling? Are any medicines or health conditions contributing? Do I need imaging or tests for arthritis or infection? How should I protect the hand while keeping it mobile?
