I did a round off (like a kart wheel) today, about 10am. I went to work after 2pm and noticed my foot started to hurt and became progressively worse that I had to leave work about 5pm. I have it elevated with ice and took Motrin 800mg. There is slight swelling on the lateral side, at my ankle. I just took the ice off and noticed the top of my foot is bruised. I cannot flex my foot without pain? Could it just be sprained or could it be bone, ligament or tendon problems? Thank you.
