A sprained ankle usually takes several days to reduce swelling.

An ankle sprain refers to an injury to the ankle joint, which typically results in swelling lasting 7 to 14 days before subsiding. If the symptoms are mild, the swelling may resolve in about 7 days. However, if the symptoms are severe, it may take approximately 14 days for the swelling to subside. The exact duration varies from person to person. Detailed explanations are as follows:

An ankle sprain occurs during walking or physical activity when the ankle joint moves beyond its normal range of motion, causing damage to surrounding soft tissues such as ligaments, tendons, and the joint capsule. If the symptoms are mild and the swelling is minimal, with the individual having good physical health, swelling usually subsides within about 7 days.

If the symptoms are severe, with significant swelling and poor physical condition, the swelling may take longer to resolve, often around 14 days. Immediately after an ankle sprain, applying cold compresses, resting, and using compression bandages can effectively reduce swelling and pain, promoting recovery.

Under a doctor's guidance, medications such as safflower oil, Yunnan Baiyao aerosol, or swelling and pain-relieving tinctures may be used to alleviate swelling. If the swelling does not subside over time, professional medical treatment at a hospital may be necessary. During the recovery period, excessive walking should be avoided, adequate rest should be taken, and a light diet, such as congee or noodles, is recommended to aid in recovery.
