Black & Blue Calf and around the ankle

I was roller blading and thought I pulled a muscle. I immediatley iced it 15on and off. the next morning my calf was bruised and so was my ankle. It hurt just to walk. But now, 2 weeks later, I can walk but it is still black and blue around the ankle and calf muscle. I think it is heeling just can not figured what I did. Let me know if anyone has had this problem. I want to know if there is something I can do to speed up my recovery time.
Thanks.
