Pain in the reflex zones of the foot may be caused by more or less pathological changes in the tissues and organs corresponding to the reflex zones. If there is pain in the reflex zones of the spleen and stomach, it is possible that the patient may have chronic gastritis, gastric ulcer or duodenal ulcer and other digestive tract diseases. If there is pain in the reflex zones of the liver and gallbladder, there may be hepatitis, gallstones, cholecystitis, and other pathologies of the liver. If there is pain in the reflex zone of the lungs, the patient may develop chronic cough or pneumonia, or in severe cases, tumors of the lungs. If the pain in the reflex zone is more obvious and there are hard nodules on pressure, the local pain area can be massaged with foot therapy to relieve the symptoms of local pain, thus also being able to treat the chronic diseases of local tissues and organs accordingly.
