i was running my gym class in socks and i was trying to slide on a mat, i stumbled a little and my big toe bent under my foot and i pretty much stepped on it. I heard and felt a crack and my toe went instantly numb. I had the nurse look at it and she suggested i go to doctor, so i did about an hour later. I had x-ray done and it showed no break. My toe currently (2 days later) is black/red from the toenail down. There is bruising that has formed on the side of my foot and also is spreading up my foot and to the left. Is there anyway to tell without tests if this is ligament damage? I've stubbed my toes numerous times and never has the bruising spread across my whole foot. The main swelling is right in the middle knuckle of the big toe.
