What should you know about a swollen bone in the hand?

After a fall, direct blow, or forceful movement, swelling over a bone may accompany a fracture even when the skin is intact. A distal radius fracture is closer to the wrist and can make the wrist and hand look puffy. Swelling beside a finger joint may instead reflect joint irritation or a small fluid-filled structure. Rheumatoid arthritis can cause tender, warm swelling in several hand joints, often with stiffness. A firm lump that grows, persists, or changes hand function needs a clinician’s assessment rather than repeated pressing or manipulation.

Stop activities that increase pain and remove rings before swelling worsens. Support the hand in a comfortable position and elevate it. For a recent injury, a wrapped cold pack may ease discomfort for short periods; protect the skin and do not apply it directly. Avoid trying to straighten, crack, or push down the bump. Keep track of its size, tenderness, movement limits, and whether the skin is warm or red. Examination and imaging may be needed to identify a fracture or the structure causing the swelling.

Seek urgent care if the hand is deformed, the fingers become pale or blue, sensation is reduced, pain is severe, or you cannot move the fingers normally. Prompt review is also needed for fever, spreading redness, an open injury, or rapidly increasing swelling. Book an appointment for a persistent lump, recurring swelling, night pain, or reduced grip. A clinician can assess whether the pattern fits a distal radius fracture, rheumatoid arthritis, or another cause of hand swelling.

Is the swelling arising from bone, a joint, tendon, or soft tissue? Do I need an X-ray or another scan? How should I protect the hand, and when can I resume gripping or lifting? What changes require urgent review?
