Thanks for the update. Sorry your son's in so much pain and I hope he feels better. Are you putting ice on it and is he resting his foot?
Once my daughter fell off a chair and landed on her elbow. We took her to the ER and the stupid doctor couldn't see the fracture on her elbow and assumed it was a dis-located elbow. So she kept twisting and turning, while my daughter screamed in agony. I was told to come back at 6:00 am to have an Orthopedic Specialist look at it and sure enough it was fractured - I was so mad and disappointed with that ER doctor.
