I landed on my ankle after jumping wrong a week ago. I rolled it but it did not swell immediately after that. I put ice on it when I got home and rested it the next day. There was still no swelling or bruising but I went to the urgent care because I couldn't walk on it without limping. They did x-rays and said nothing is broken and told me I sprained my ankle. They wrapped it in an ace bandage and put on an aircast. Now it is a week later and I still can't walk on it without pain but there is no swelling or bruising, just tenderness along the outside of the ankle that wraps around to the top of my foot. What should I do?
