so i assume he has you on crutches, hopefully they gave you some vicatin for the pain. in some cases its better to break it then to sprain it because the sprains take longer to heal. if they find a fracture they will probably put you in a walking boot, i wouldnt think they would cast it up but maybe if its real bad. everything else i am sure they told you, ice it keep it elevated and its good if its a bunch of nasty colors, thats signs its healing, its when there isnt color or any real swelling but still lots of pain thats when it usually is much worse
