There is no pain whose cause is obvious and immediately attributable to a localized dysfunction. Often the origin of the pain is to be found in areas other than those affected. For example, a common backache may result from excessive fatigue in the foot or a malfunctioning jaw. Similarly, would you ever have imagined that overloading the intestines can induce headaches? Our body is a machine with complex gears and countless transmission belts. Being able to find the right key to interpret when the warning light of pain turns on, identifying its origin, looking at the patient in all his complexity, and being able to guarantee him lasting benefit are the greatest satisfaction that this work can give me.
