<human>: I have a swollen ankle. What is it and how can I treat it?
<bot>: Your ankle may be sprained or swollen due to an injury. It is important to rest the affected area and apply ice for 20 minutes every two hours, elevate your foot above your heart, and use compression bandages to reduce swelling. If you experience pain or increased swelling, contact your doctor. You may also want to consider using an over-the-counter anti-inflammatory medication such as ibuprofen.
