A Medical Doctor explains chiropractic.
"The head weighs between eight and 14 pounds. It must remain in perfect alignment in order to prevent interference in every brain-to-body function. Misalignment can result from automobile accidents, poor posture, falls and countless other causes. When the head becomes misaligned, it reacts adversely with pain and poor health. This is where upper-cervical chiropractic intervention comes into play. There is no forceful twisting or pulling of the neck. Muscles relax, blood circulation increases, and healing begins."
-Dr. Peter Gott MD (1.)
As a result of fearful, traumatic, or forceful births your neck may be out of alignment.
