Swelling on a hand joint: what to know

A joint that swells after a knock or twist may be sprained or fractured. Repetitive gripping can irritate the joint lining and nearby tendons. Warmth, prolonged stiffness, or swelling in several hand joints can occur with inflammatory arthritis; rheumatoid arthritis commonly presents with swollen, painful small joints. A distal radius fracture can cause swelling that reaches the wrist and hand after a fall. A hot, red joint with fever is different from ordinary activity-related soreness and requires prompt assessment.

Remove rings before swelling progresses. Rest from forceful gripping, support the hand comfortably, and use a cloth-wrapped cool pack briefly after a recent injury. Keep fingers moving gently within a comfortable range unless a clinician has told you to immobilise them. Avoid tight wrapping and do not puncture or drain a swollen joint. A clinician may assess alignment, stability, tendon action, sensation, and circulation, then decide whether imaging or other tests are needed.

Seek urgent care for deformity, a finger that will not move, new numbness, blue or pale skin, or severe swelling after trauma. Get prompt medical advice if the joint is hot and red, pain is severe, redness is spreading, or fever develops. Make an appointment when swelling lasts, recurs, or limits writing, dressing, cooking, or other hand use.

Which joint structure seems affected? Is an X-ray appropriate? Could inflammation be involved? How can I maintain movement without aggravating the joint, and when can I return to gripping activities?
