Swollen Ankle... Help?

I landed on my ankle weird while I was at ultimate practice today. I landed on the outside of my foot because of a huge pothole and my foot was bent in suddenly. I can walk so I know it isn't sprained but my ankle is pretty swollen. I got home and iced it for about an hour, doing it 15 mins at a time and taking a small break. Then I soaked my ankle in warm water for a good half an hour. I've taken Ibuprofen and I have an ankle brace on. The swelling won't seem to go down at all but I don't feel pain when I was, except for the occasional jolt when I walk on uneven ground. I heard that icing it doesn't help after a day so I don't know what else to do. Please help?
