Last month I jumped off the tailgate of my truck and landed hard on the ball of my right foot. Now it hurts whenever I'm on my feet for a long time, or when my big toe gets bent upward. Could I have broken my big toe?

It's more likely that you hurt the two small bones under the main joint of the big toe, the sesamoids. The impact may have caused inflammation in the soft tissues around the sesamoids. This condition is called sesamoiditis. You should tell your doctor about your injury. It is possible that your jump caused a fracture in one or both of the sesamoid bones.
