Many people do not know this, but the first Chiropractic patient was a deaf man who regained his hearing after having his spine adjusted. While your grand-daughter's deafness could be caused by many different things, it is always recommended new born babies be checked by an Upper Cervical Doctor as soon as possible. The birth process is very traumatic on their neck, neck bones, and spinal cord, and we would want to make sure that she is ok in that area. At the same time, our doctors could better assess if the deafness is caused by a problem in her neck, or if it is something else.
