Kidney deficiency may be characterized by heat in the chest, while kidney yin deficiency may be characterized by heat in the hands, feet and heart, and irritability and heat in the chest. Not all kidney deficiencies are characterized by chest heat. Kidney deficiency can be divided into kidney yin deficiency and kidney yang deficiency. Kidney yang deficiency is characterized by fatigue (mental exhaustion, physical weakness), lack of energy, low vitality, easy fatigue, fear of cold, cold limbs and other symptoms. Kidney yin deficiency is mainly manifested by symptoms such as five heart-heat (heat in the hearts of the two hands and two feet, and self-consciousness of the heart and chest), hot flashes and night sweating (abnormal sweating after going to sleep, and sweating stops after waking up), lumbar and knee pain, dizziness and tinnitus, insomnia and dreaminess, and other symptomatic manifestations. The treatment is mostly to nourish yin and tonify the kidneys, and commonly used Chinese medicines such as Liu Wei Di Huang Wan and Zuo Gui Wan are used for treatment. Chest heat caused by kidney yin deficiency needs to be treated under the guidance of a professional doctor after identifying the symptoms. According to the condition, choose traditional Chinese medicine, acupuncture, massage and other methods of treatment. Avoid spicy and stimulating food.
