Injuries can be divided into two categories. Flesh and bone injuries are mostly visible as external signs and are collectively referred to as external injuries. As opposed to external injuries, mainly qi and blood loss, visceral injury of a class of evidence is generally known as internal injuries, also known as internal damage. Internal injuries can be divided into acute, slow, new, old and other types of evidence. Where the fall and fall suddenly caused by acute injury, such as the lack of labor, accumulation of labor for a long time caused by chronic injury. Only by a single injury, or a short period of time after the onset of the injury is a new injury. If a long time ago, the injury again, or the new injury is not cured and lingering for a long time are old injuries. The above urgent and slow new Chen regardless of what type, its pathogenesis are Qi and blood imbalance, the internal organs involved. Therefore, the clinical diagnosis can be qi and blood as the outline, refer to the internal organs, see the symptoms of analysis, and grasp the disease. A. Causes The factors that lead to the occurrence and development of internal injuries are both internal and external. These factors act on the body to produce a series of reactions and symptoms. The human body’s response to external damage factors, although there is a general rule, but because of the human body’s physiological characteristics and pathological factors are different, so the human body to external damage factors have a variety of special reactions. 1, external factors mainly refers to the external action on the human body injury-causing factors, such as external violence and strong weight. External violence suddenly invade the human body, such as: falls, falls, flash setback, boxing, beating, etc. Strong weight injury: due to the weight or force more than its own capacity, strong endurance and lead to injury. 2, internal causes Mainly refers to the injury-causing factors that affect the human body from within. Such as the patient’s physique, age, local anatomy, labor position, lifestyle habits, etc. Old age and weakness, liver and kidney essence and blood deficiency, the slightest external attack will be easy to occur internal injury. Local structural weakness or lesions, poor labor position and living habits are also easy to cause injury. Second, the symptoms of the diagnosis of internal injuries, mainly in how to recognize whether the injury is qi, blood, or both qi and blood injuries. And then according to the injury after the flow of qi and blood injection parts, decided or injury tendons, or injury bone. Now, respectively, as follows: 1, injury to the gas: most of the chest is tight, weakness, conscious heartbeat, pain without a fixed location. 2, injury to blood: vomiting blood, blood in the stool (persistent episodes), weakness, abdominal distension, or abdominal pain, the pain is fixed and does not move. 3.Stasis of blood: itchy throat, coughing, feeling stuffy when vomiting blood without vomiting, feeling refreshing after vomiting blood, weakness, shortness of breath, atrophy. 4.Both qi and blood injury: like the first injury to qi and then to blood of the breath injury, vomiting blood with chest tightness, cough. All internal injuries, regardless of injury to gas, blood or gas and blood injuries, a few start without pain, slow development by the symptoms appear, but the development of different speed, but also illustrates the difference in severity. Generally, those who appear quickly are lighter and those who appear slowly are heavier. Injury is due to both qi and blood, injury to qi is qi stagnation, injury to blood is blood stasis, so the treatment is also based on the management of qi and blood. And because qi is the handsome blood, so to regulate the qi first. However, there is also defeated blood stagnation, thus blocking the path of qi flow, that is, first to defeat the blood, and then to regulate the qi, which all depends on the clinical evidence of the adaptations.
