<human>: I have a swollen ankle. What is it and how can I treat it?
<bot>: You may have sprained your ankle, which is when the ligaments in the joint are strained or torn. This can happen from overuse or an accident, such as falling down. It’s important to rest your ankle and elevate it above your heart for 24-48 hours. You should also apply ice packs to reduce swelling and pain. If you still have pain after 48 hours, see a doctor.
