Bruising With a Sprained Wrist

A fall onto the hand can also cause a fracture that resembles a sprain. Marked tenderness over a bone, visible deformity, or difficulty using the hand calls for examination rather than relying on the appearance of the bruise.

A sprain affects the bands of tissue that stabilise the wrist bones. Bruising shows that tissue has been injured, but its colour or size cannot reliably reveal the injury grade. Pain may be worse with gripping, pushing up from a chair, or turning a key. Tenderness on the thumb side after a fall deserves particular attention because some fractures are initially easy to mistake for a sprain.

Remove rings, watches, or tight bracelets before swelling increases. Rest from lifting and gripping, cool the area through a cloth for brief periods, and keep the hand raised when practical. A properly fitted splint can limit painful motion, but it should not make the fingers numb, cold, discoloured, or more painful. Move the fingers gently and do not tighten a wrap to the point that circulation is affected. Avoid repeatedly bending the wrist to check whether it has recovered.

Seek urgent help if the wrist is misshapen, a bone or deep wound is visible, or the fingers become pale, blue, cold, numb, or weak. Prompt assessment is sensible after a forceful fall if pain is severe, swelling is substantial, there is precise tenderness over a wrist bone, or you cannot grip and use the hand. Arrange follow-up when pain is not settling, movement remains limited, or the wrist feels unstable during ordinary tasks.

Ask whether the examination can distinguish a ligament injury from a fracture and whether imaging is needed now or after reassessment. Confirm how long to use a splint, which finger and wrist movements are safe, and when strengthening should begin. For work or sport, ask which gripping, lifting, and weight-bearing tasks should be restored before full return.
