About 8 months ago, my 14 year old daughter's left arm was trampled on accidentally by a schoolmate during a sporting activitiy. X-ray showed no injuries. But the pain has persisted. Pain comes and goes. Lately she has been complaining of pain that runs down the arm to the tip of fingers and even up to back of neck and head. Pain sometimes goes to the other arm too. Should I take a to a neurologist and what x-ray do you suggest?
