How common is ankle swelling in ankle sprain?

A sprain stretches or tears one or more ligaments that help steady the ankle. The body responds with local inflammation, which can produce puffiness around the outer ankle and sometimes into the foot. Swelling may change during the day and increase after too much activity. Because fractures can follow similar mechanisms, swelling by itself cannot distinguish a sprain from a broken bone.

Protect the ankle from movements that cause sharp pain, elevate it when resting, and use a wrapped cold pack if comfortable. Gentle movement within a tolerable range can help prevent stiffness; avoid forcing the joint. As walking becomes easier, a clinician or physiotherapist can guide balance and strengthening exercises so the ankle regains control before demanding sport or uneven-ground activity.

Arrange an assessment if you cannot take a few steps, pain is focused directly over a bone, or swelling and bruising are substantial. Seek urgent care for deformity, an open injury, numb or cold toes, or rapidly increasing pain. Review is also useful when swelling is not settling or the ankle repeatedly gives way during recovery.

Could I have a fracture as well as a sprain? When should I begin balance and strengthening work? Do I need a brace for walking or sport? What change in swelling or walking should prompt a follow-up?
