1. Rest: Avoid putting weight on the injured ankle and try to keep weight off it as much as possible. Use crutches or a cane, if necessary, to relieve pressure.

2. Ice: Apply ice packs or cold compresses to the injured area for 15-20 minutes at a time, several times a day, especially during the first 48 to 72 hours. This can help reduce pain and swelling.

3. Compression: Wrap the ankle with an elastic bandage to provide support and reduce swelling. Make sure the compression is firm but not too tight, as it could restrict blood flow.

4. Elevation: Keep your ankle elevated above the level of your heart as much as possible. This can help reduce swelling and promote healing.

5. Pain relief: Over-the-counter pain relievers like acetaminophen or ibuprofen can help alleviate pain and reduce inflammation. Follow the recommended dosage instructions and consult with a healthcare professional if needed.

6. Rehabilitation exercises: Once the acute pain and swelling subside, you can start doing gentle range-of-motion exercises and strengthening exercises recommended by a healthcare professional or physical therapist. This can help restore mobility and strengthen the ankle.

7. Professional evaluation: If your symptoms are severe, the pain persists, or you suspect a more serious injury, it's important to seek medical attention. A healthcare professional can assess the extent of the injury and provide appropriate treatment recommendations.

Remember, these are general suggestions, and it's always best to consult with a healthcare professional for a proper evaluation and personalized advice based on your specific situation.
