What Causes Swollen Ankle And Bruising Around The Bottom Of Foot?

I rolled my ankle playing basketball last Sunday. My ankle is still swollen and there is bruising around the bottom of my foot , ankle and in-between some toes. I am now able to walk pretty good on the ankle and it is getting better. Today I started have bad pain in my calf. It was very stiff and tight after I rolled my ankle and now it feels like a tight ball rolled up inside my calf. Is this normal?
