How common is hand swelling in complex regional pain syndrome?

In complex regional pain syndrome, swelling may fluctuate and can affect the hand, fingers, or a larger part of the limb. The skin may feel unusually warm or cool, and light touch or movement may be very uncomfortable. Stiffness can make it harder to open the hand or use the fingers normally.

Hand swelling has many other causes, such as injury, infection, inflammatory joint problems, circulation changes, or fluid retention. A clinician will consider when it began, whether there was an injury or procedure, how the skin looks, and whether movement and sensation have changed.

Arrange medical review when swelling persists after an injury, is paired with disproportionate pain or marked sensitivity, or limits finger movement. Keep the hand moving gently within tolerable limits, protect it from knocks, and follow any plan provided by your clinician. Avoid forcing stiff fingers or applying extreme heat or cold to a very sensitive area.

Early, coordinated care may focus on comfortable movement, desensitisation, swelling management, and restoring everyday hand use. The plan should be adjusted to your symptoms rather than pushed through severe pain.

Seek urgent care for rapidly increasing swelling, severe pain, a hand that becomes blue or cold, fever with spreading redness, drainage from a wound, or new loss of movement or sensation. Sudden breathlessness or chest pain alongside limb swelling is an emergency.

What findings support complex regional pain syndrome? Could infection, fracture, or circulation problems explain the swelling? Which movements are safe now? How should I protect the skin and manage sensitivity? When should swelling or color change be treated urgently?
