While playing tennis i went for the ball and my right foot turned on its side (causing it to be perpendicular to the ground instead of flat parallel) i feel like a bone may be out of place but im not sure. The side it turned on is definitely swollen and i can barely walk from the pain. I can not tell if its turning black or not but as time goes by the pain and swelling is increasing. It now feels as if i also have a cramp going through the middle of my foot horizontally from where i can feel the possible out of place bone.
