i run 5 miles p/day and play soccer or bball at night. last night, my bf and i were playing soccer and as i was running past him, he grabbed my right shoulder and then i felt a grueling pain ont he top of my right foot. the pain is more on the left side of my right foot and it's very difficult ot walk let alone run. i swam this morning bc i couldn't run. any idea what it is? strain?
