Scholl Orthaheel Gel Heel Pain Reliever. Did you know more than 70% of people in the world have got a tendency for their foot to roll-over inside, and gradually flatten? As the foot flattens out on the ground, the supporting tissues that run along the bottom of the foot (the plantar fascia) are stretched. If these forces are excessive they can lead to stress and inflammation of the tissues, causing pain under the heel when weight is placed on the foot. Pain in the back of the heel can be caused by inflammation of the tissue that connects the calf muscle to the heel bone (Achilles tendon). The pain can result from the position and movement of the foot causing the tendon to be stretched. It can also be caused by injury.
