What is the pain in the back of the sole? Is it kidney deficiency?

The pain in the back of the sole plate may be caused by overwork, trauma, plantar fasciitis and other factors. The specific analysis is as follows: 1. Overwork for a long time walking, weight bearing, transportation, etc., will lead to increased weight bearing in the back of the sole plate, local congestion, and peripheral nerve sensitivity, resulting in the above situation. 2. After trauma, the soft tissue of the sole is damaged, the capillaries rupture, resulting in local hematoma, increasing the pressure on the sole, which will lead to pain at the rear of the sole. 3. Plantar fasciitis Plantar fasciitis will cause aseptic inflammation and infection in the sole, and the congestion, edema, exudation and exudate of the plantar fascia will stimulate the surrounding tissues and cause pain. The pain in the back of the sole may be caused by kidney deficiency or other factors. Kidney controls water. After kidney deficiency occurs, it will affect the balance of water in the body, causing imbalance of water circulation in the limbs, causing swelling of the sole, increased pressure, stimulation of peripheral pain nerves, and thus pain in the back of the sole. However, bone spur will also rub the sole part, resulting in local swelling, congestion, thus stimulating the peripheral sensory nerves, there is pain in the rear of the sole. If you need to clarify the cause, you should see a doctor in time, through consultation, percussion, B-ultrasound examination, CT examination, magnetic resonance imaging examination and other ways of diagnosis.
