Pain in the center of the sole of the foot, at KI-1 (Gushing Spring, 湧泉 yǒng quán). It is usually due to kidney vacuity damp fixity and the life gate fire failing to spread warmth, in which case it is associated with heat pain in the ankle bone and treated with Kidney Fixity Decoction (肾着汤shèn zhuó tāng) combined with Eight-Ingredient Pill (八味丸bā wèi wán). Pain in the heart of the sole may also be attributable to streaming damp phlegm, which is observed in obese people and is experienced when the patient walks after long sitting or lying. This is treated with Kidney Fixity Decoction (肾着汤shèn zhuó tāng) combined with Mysterious Two Powder (二妙散èr miào sǎn).
