Sprained ankle can be reduced by resting and braking, cold compresses, pressure immobilization, elevation of the affected limb, application of drugs to reduce swelling and pain. 1. Rest and braking: rest sufficiently, limit the activity of the affected area. 2. Cold compresses: cold compresses are applied within 72 hours during the acute stage, and then hot compresses are applied to promote the absorption of local tissue exudate as soon as possible. 3. Pressure fixation: bandage can be used to increase the stability of the ankle joint. 4. Elevate the affected limb: you can put a pillow under the affected foot to elevate it when sleeping, so as to increase venous and lymphatic return and help reduce the swelling. 5. Apply medication: Pain can be treated with painkillers such as ibuprofen and acetaminophen under the guidance of a doctor if the pain is severe. Sprained ankle is recommended to consult a doctor in a timely manner, under the guidance of the doctor to carry out standardized treatment, to avoid delays in the condition.
