Hi. I am a Chiropractor and have mentioned your question to my good friend and colleague Dr. Rhonda Emmert. She is also a chiropractor and specializes in psychoneuroimmunology and children's health in particular. This is what she had to say:
"Has your son been ruled out for right hip socket congenital anomalies?. Is there history of Thyroid illness or Diabetes in your family?
Leg and hip problems like this are prevalent due to insufficient adrenal function. And Adrenal function is correlated with Thyroid problems or Diabetes. Does your child also have mood issues, allergies or Asthma?"
I would suggest that first you find out about hip socket anomalies and then you could look into what you can do to support his adrenal function.
Dr. Emmert is working on a web site where she will have information available about issues such as adrenal insufficienies, etc., but it is not up yet.
I have posted a short biography when she answered another question, but I will post it here again for your information,
Rhonda Emmert, D.C., B.A. Nutrition, is co-founder of essencehealers/Patient Advocacy through Molecular Mindfulness, and has been practicing for 23 years in San Francisco. Dr. Emmert, was voted one of the ten best chiropractors in San Francisco Magazine, and is listed in America’s Top Chiropractors, 2007. She has built her practice by addressing her patient’s obscure and chronic conditions. She has devised a system of analysis, Molecular Mindfulness, that utilizes biochemistry as the avenue to systemic diagnosis. Dr. Emmert has a family-based practice; hence, she has seen the genetic implications that warrant biochemical healing at the deepest level. She takes her patients on for life.
I hope this helps, Dr. M. Herman
