If there is no swelling in the effected area then she doesn't have a fractured bone, yes the answer above was common sense but it is always best to start at the most common cause which can be overlooked very easily. Believe me it was in no way intended to insult you in any way but it is best to cover all the basics first. It could possibly be a tissue injury, most likely a bruise. If she done better after the alcohol was applied then I would continue doin it, it acts as a type of pain reliever for muscle bruising, strains and cramps. She could have easily caused injury to her pad by doing something as small as stepping on a rock that was just sitting at a bad angle.
