Swelling after surgery: what should I do?

Why swelling happens after surgery

Some swelling around an operation site is a normal part of healing. The body sends fluid to the area as it repairs, and this can make the limb feel tight and stiff.

Swelling is often worse later in the day, or after the limb has been down for a while. It usually settles slowly over the healing period.

Knowing what is normal helps you stay calm, while still watching for the signs that are not.

It also helps to know what to expect over the coming days, so ordinary healing does not cause worry. We are glad to explain what is likely normal for the particular operation.

What helps swelling settle

Raising the limb when resting often helps fluid drain away, within your surgeon’s advice. Gentle, allowed movement of the area also helps, since muscles moving act like a pump.

Following your surgeon’s guidance on rest, ice or compression matters, as this differs between operations.

A physiotherapist can guide how much movement is right for your stage, so swelling settles without straining the healing part.

Blood clot warning signs to act on

One serious cause of swelling needs urgent care. A blood clot in the leg can cause a calf that is hot, swollen and painful, often on one side.

If a clot travels to the lungs it can cause sudden shortness of breath or chest pain. These signs need urgent medical review, not exercise.

If you notice them, seek medical care straight away. It is always safer to be checked.

Other signs that need a doctor

Beyond a clot, some swelling points to another problem. A wound that turns red, hot, or starts leaking, along with swelling and a fever, can mean infection.

Swelling that suddenly gets much worse, or a limb that turns pale, cold or numb, also needs prompt review.

A physiotherapist watches for these signs too. If we see them during a visit, we pause and help you get the right care.
