Hao Shi said: Then, "strong pain in the head" is the meaning of headache Xiang Qiang, the pronunciation of the word strong is "craftsman", the headache is mainly the back of the head pain, "Xiang Qiang" is mainly the back of the neck is not soft, because the head and the back of the neck are the parts of the sun meridian through.
"Strong pain in the head" is a manifestation of the evil in the sun meridians and unfavorable essence, so this symptom is a positioning symptom for diagnosing sun disease, if there is only a floating pulse, there is no "strong pain in the head", you cannot diagnose sun disease.
For example, if this person has a floating pulse, migraine, deafness, and red eyes, and the pulse is light, then you may be diagnosed with Shaoyang meridian and have a headache.
If this person has a sore brain, eyes, dry nose, and red face, and the pulse is taken lightly, it is the Yang Ming meridian that is evil, and that is the manifestation of the Yang Ming Sutra.
Only when there is a "strong pain in the head" and "pulse floating" can we know that it is the sun meridian that is affected by evil, and this can be diagnosed as the "sun manifestation".
The last symptom of the sun's sign is "and cold", this word is a conjunction, but it does not mean a juxtaposition, but it means an advanced layer, it is an advanced conjunction.
Then the advanced conjunction, when we translate into modern Chinese, we should translate it like this, the sun is sick, the pulse is floating, the headache is strong, and we will definitely see the cold, it has a certain meaning, and we will definitely see the cold.
Because the sun is a symptom of the wind and cold evil qi damaging the yang energy on the human body's surface, then the yang energy on the body surface is injured by the wind and cold evil qi, and the yang qi is insufficient, and the yang temperature and warm skin are dysfunctional, so that he naturally feels afraid of cold.
What is the function of the sun's yang energy? It is to warm the skin. Now the yang energy of the sun is injured by the evil energy of wind and cold, and the function of warming the skin is insufficient, of course, this is the first signal. The first feeling of the human body is that it is afraid of cold, and cold is afraid of cold, so later generations of doctors believe that "there is a point of cold and a table".
But when the kidney yang is insufficient and the surface yang is helpless, at that time it is really the surface yang deficiency, and it can also have cold. So this cold is an external cold? Or is it a deficiency of surface yang caused by the deficiency of yang? Then it must be combined with the pulse float, then the pulse float must be the external cold injury of the yang, so only these three symptoms are combined, the pulse float indicates that the evil is on the surface, the strong pain in the head indicates the evil in the sun meridian, and the evil cold indicates that the external wind and cold evil qi hurts the yang qi of the sun, only when these three symptoms are combined, we can judge that this is the sun manifestation.
Therefore, as a solar manifestation, these three symptoms should be present, and none of them is indispensable, and a single symptom cannot be diagnosed as a solar manifestation, and the reason why it is used as an outline is that it first reflects that the main symptom of solar disease is the manifestation.
Secondly, it embodies the manifestations of sun disease, which should be characterized by pulse floating, strong pain in the head and chills, and meet these two conditions, so it can be used as an outline of sun disease. In particular, we should be reminded that, as an outline of the Sutra, it only speaks of the main symptoms of the disease.
For example, if you talk about sun disease, it has secondary symptoms, there are metamorphoses, and there are similar symptoms, and this outline cannot include its non-major symptoms. Like the secondary syndrome and the change syndrome, it mainly represents the main symptomatic manifestations including it.
Of course, for sun disease, after the cold evil hurts the surface, the yang energy of the human body rises up to resist the evil, and the yang energy appears pathologically excited. What about the symptoms? There will be a fever, so for sun sickness, it will definitely have a fever throughout its course.
Therefore, later generations of doctors said that as an outline of sun disease, it lacks fever, and if there is no fever, how can it be said that it is a sun disease?
In fact, because of the fever of sun sickness, some can appear first, and some can appear later, so it is no longer mentioned in the outline.
With these three symptoms, as long as there is a floating pulse, it indicates that the righteous qi can resist the evil on the surface, which can be used as an outline of the sun disease.
Then, due to the difference in the constitution of the human body and the difference in the nature of feeling the evil qi, there can be different classifications of sun diseases.
