Pain in either or both heels that is usually unassociated with swelling yet makes walking difficult. Heel pain is a sign of kidney vacuity. If associated with intermittent heat in the lower leg, it is due kidney yīn vacuity. If associated with inability to stand for long periods it is due to kidney yáng vacuity sign. In some cases, dampness may collect in the heel causing local swelling. Damp-heat may also be observed.
Medicinal therapy: Kidney yīn vacuity is treated by supplementing the kidney and enriching yīn with Six-Ingredient Rehmannia Pill (六味地黄丸liù wèi dì huáng wán) or Four Agents Decoction (四物汤sì wù tāng) and variations. Kidney yáng vacuity is treated by supplementing the kidney and warming yáng, using Cinnamon Bark and Aconite Eight-Ingredient Pill (桂附八味丸guì fù bā wèi wán).
