The humb in your back is due to stones in the liver and the gallbladder. The meridiens that pass through these organs also pass through that part of your back and affect the circulation and waste removal there. This is not a hereditary problem as such, but similar lifestyle and dietary habits can lead to similar problems among family members. It is not responsive to taking calcium. Poor bile secretions lead to reduced calcium absorption. Ingesting more calcium doesn't mean you absorb it. Removing the thousands of stones that cause the hump is a more efficient way.
