What to know about a swollen, sore back of the hand

A clear knock or overuse pattern may point toward bruised or strained tissue. Heat, spreading redness, a wound, or worsening tenderness makes infection more concerning.

Pain over a precise spot after impact can arise from a bruise, ligament injury, tendon irritation, or fracture. Pain when straightening a finger may involve the tendons running across the back of the hand.

A tender lump may represent a cyst or local inflammation, while widespread puffiness can extend from the wrist or fingers. Symptoms beginning without a hand injury may also relate to joint inflammation, fluid retention, or irritation coming from another nearby structure.

Take off rings and snug wristwear before swelling increases. Pause lifting and forceful gripping, support the hand in a comfortable position, and elevate it when resting.

A cloth-wrapped cold pack can soothe a recent closed injury. Keep cuts clean and covered, but do not press, drain, or massage a painful lump. If normal finger or wrist use does not return, a clinician can examine the bones, tendons, joints, and skin.

Arrange urgent care after trauma when the hand looks misshapen, you cannot move a finger, pain is intense, or numbness develops. Fingers that turn pale, blue, or cold may have impaired circulation and need immediate assessment.

Obtain same-day help if soreness and swelling rapidly worsen, redness spreads, the skin feels hot, pus appears, or you develop fever. Puncture wounds and bites can introduce infection even when the surface opening looks small.

Ask which structure appears injured, whether an X-ray or other test is needed, and whether a splint would protect movement. Clarify how to use the hand at work, which exercises are suitable, and what worsening changes require reassessment.
