My 14 yr. old son has chronic pain from his neck to his lower back. He describes it as more of an uncomfortable, tingly feeling more than pain, but it bothers him nonetheless. We went to physical therapy for a while, and the exercises seemed to help him a little bit, but the pain has just recently gotten worse. He does not play sports, and x-rays were taken of his back and revealed nothing wrong. We are baffled as to what is causing the pain, we were wondering if it could be related to his posture, and also his gait is off as he often "in-toes" without even knowing it. Could this be related to the pain? Please, any replies would be great. Thank you.
