What should you know about hand joint swelling?

A joint may swell after a sprain or repeated strain, or because its lining is inflamed. Osteoarthritis often causes activity-related aching and stiffness, while rheumatoid arthritis can present with several swollen, stiff joints. Psoriatic arthritis may accompany psoriasis or changes around a nail. Gout and pseudogout are crystal-related causes that can produce a sudden, very painful, warm joint. These patterns are clues, not a diagnosis.

Record which joints are involved, whether both hands are affected, how quickly swelling appeared, and whether morning stiffness, warmth, fever, skin changes, or an injury is present. Examination and, when needed, tests can distinguish these possibilities.

Rest from activities that clearly worsen the swelling, but gently move the fingers within a comfortable range to prevent stiffness. Elevate the hand and use a wrapped cool pack for short periods. Remove tight rings. Avoid starting leftover medication or combining pain medicines; a clinician or pharmacist can advise whether anti-inflammatory medication is appropriate for your health history.

If swelling keeps returning, arrange an appointment. A clinician may discuss hand exercises, splinting, anti-inflammatory medication, or a cortisone injection depending on the cause and examination findings.

Seek prompt medical care for a hot, intensely painful joint with fever or feeling unwell, rapidly spreading redness, or a wound nearby. Urgent assessment is also needed after significant trauma, when a finger looks deformed, or when you cannot move or use the hand. Sudden weakness, numbness, or a pale or blue hand requires emergency help.

Which pattern does my swelling suggest? Do I need imaging or blood tests? Would hand therapy, anti-inflammatory medication, or an injection be suitable, and what risks apply to me?
