Heart and Lung Areas of the Feet
When I see some abrasion or calloused skin on the ball of the foot, then I know that there’s some heartache there. If it is yellowed, then it’s an old issue. If it’s black, there’s some anger there.
Usually the esophagus area is in the lung area of the foot, and if there is some callousness there, I realize that there’s something hard to swallow.
