Buzzing in the ears is a symptom of tinnitus, which is not necessarily caused by kidney deficiency. According to traditional Chinese medicine, tinnitus can be categorized into lung and spleen qi deficiency, liver fire inflammation, and kidney essence deficiency depending on the cause and manifestation of tinnitus. Generally, tinnitus caused by kidney essence deficiency is usually high-pitched tinnitus, which sounds like cicadas, and may be accompanied by neurological hearing loss, as well as soreness and weakness of the waist and knees, long and clear urination, and loose stools, which are symptoms of kidney essence deficiency. If it is accompanied by emotional impatience and irritability, bitter mouth and dry throat, etc., it may be caused by excessive liver fire. If accompanied by dullness and fatigue, poor diet, etc., it may be caused by the deficiency of lung, spleen and qi.
