My son and I were in a car accident in mid april and he has been complaining of his back since about a week after the accident and no one would listen to me! I took him to urgent care a couple of weeks ago about the problem and had them take xrays... they shortly dismissed it as nothing, and the pain hasn t eased up! When the pain flares up he refuses to play, wants to lay down, and screams in pain when anyone tries to touch the area I have also noticed a swelling in his lower back that comes and goes on a daily basis. His pediatrician also tried to dismiss me as an over reacting mom but decided to get xrays done again, however, she told me i was crazy when i told her about the swelling! I would like a second opinion on my concerns! Can someone please tell me if this is a possible serious problem?
