Chapter 49 Reset
"Can it be cured?"

Yong Hongzhong asked in surprise and joy, during this period of time, he was tortured by this unknown and strange disease that made him dizzy when he crouched down.
But it is still possible to experience nausea and even vomiting every night when lying down in bed.

Li Ang nodded calmly, "Yes."

"Doctor Li, what's wrong with my husband?"

The old servant Yong Hongzhong on the side asked respectfully, and the address changed from "Little Langjun" to "Physician".

Benign paroxysmal positional vertigo.

Or, otolithiasis.

Li Ang pondered the answer silently in his heart.

As a vertebrate, the reason why humans can balance themselves during exercise is mainly because the ears have organs that regulate the balance of the body.

The organ consists of three tubes and two sacs. The three tubes refer to the anterior semicircular canal, the posterior semicircular canal and the horizontal semicircular canal, which are responsible for the angle of the sensory head.
The two sacs refer to the balloon and the utricle.

In the structure of the two capsules, there are some calcium carbonate crystals, which look like small stones or chalk powder, so they are also called otoliths.

The otoliths are usually fixed in the two capsules, which assist the two capsules to sense the acceleration of the head and transmit the position signal to the central nervous system through nerves.

It is precisely because of the three tubes and two sacs that humans can "perceive" the balance and gravity of their bodies, and will not fall on the ground or feel like the world is spinning.

If the otoliths in the two sacs fall off due to some special reasons, it will cause an interlocking reaction - the falling otoliths will swim in the endolymph fluid of the inner ear,

When the position of a person's head changes, the otoliths will stimulate the semicircular canal hair cells, causing the semicircular canals to be exposed to wrong signals, causing strong dizziness in the human body.

Otolithiasis is more common in middle-aged people, and women are slightly more likely to be caused by head trauma, strenuous exercise, long-term staying up late, or middle ear and inner ear surgery.

Just now, Li Ang first ruled out the possibility of Meniere's disease and migraine through physical examination and inquiries.
He also passed the Dix-Hallpike displacement test, that is, holding Yong Hongzhong's head, guiding him to lie down on his back quickly, and actively letting the otoliths touch the semicircular canals to induce dizziness.

It was finally determined that he had posterior semicircular canal otolithiasis.

(Posterior semicircular canal otolithiasis, that is, the otolith has moved to the position of the posterior semicircular canal. When this happens, the Dix-Hallpike displacement test will only cause nystagmus when the affected side is turned to the side. Nystagmus does not occur on one side. In anterior semicircular canal otolithiasis, nystagmus occurs on both sides)
Of course, these processes are not easy to tell everyone in front of them.

Do people rely on the stones in their ears to grasp their position?

This is a bit too bizarre.

You must know that in the memory of another world, doctors discovered otolithiasis in 1921, but it was not until 1980 that a doctor named John Epley realized that the cause of otolithiasis was the falling off of otoliths. Reduction manipulation in the treatment of patients with otolithiasis.

In the middle of the process, doctors cure otolithiasis by severing the vestibular ganglia—a consequence of which is the loss of hearing and balance.

Moreover, even after John Aprily proposed that otolithiasis could be cured by repositioning, his research results were not widely recognized, but were ostracized, ridiculed, and even accused of illegal medical practice by his peers.

Li Ang's mind turned sharply, and it was difficult for him to convince the people in front of him that the reason why people could feel gravity and position changes was because there were stones in their ears.

Even if persuaded, there is no evidence, but people will suspect that he secretly did something shocking such as autopsy of a corpse.
The medical level of Yu country is relatively backward compared with architecture, materials science, astronomy, etc.
On the one hand, this is because the monks in the Academy rarely get sick and have no motivation to promote development.

On the other hand, it is because the act of dissecting and studying human corpses was taboo in both the former Sui and Yu dynasties—this is almost a demonic act.

Li Ang still remembers Pu Liuxuan's persuasion that he must be admitted to the entrance hall before he can have social status, the foundation of his life, and the right to speak and influence.

Doctors must protect themselves before they can protect their patients.

In the blink of an eye, Li Ang had weave a set of rhetoric that could be accepted by the people around him, and said without changing his face and heart: "Although there are many causes of vertigo, they are nothing more than reality and reality.

Deficiency is mostly due to deficiency of qi and blood, insufficient marrow sea, and dystrophy of clear orifices.

Brother Hongzhong recently studied too hard and used too much energy. In addition, his body was weak and the supply of qi and blood was insufficient, which caused dizziness. "

"I see."

Song Shaoyuan and the others showed the expression of "Oh, so that's how it is, um, I fully understand it now", and nodded.

Qiu Feng faintly felt that something was wrong, he frowned and looked at Li Ang, hesitating to say anything.

"Then Doctor Li, do you want my husband to eat more meat?"

Yong Hongzhong's personal old servant respectfully asked,

Li Ang shook his head and said, "Eat more absolutely cooked beef, mutton, and fish, and not drinking raw water is one aspect.

On the other hand, it has to be assisted by manual reset.

That is to rotate the mind, let the blood in the heart flow to the head, and unblock the head's qi.

Combining the two methods can be completely cured.

Come on, Brother Hongzhong, sit down again. "

Li Ang asked Yong Hongzhong to sit again on the table, supported his head again, and turned his head 45 degrees to the left side of the affected ear.
Then pull the head and guide Yong Hongzhong to lie down, with his head slightly protruding from the edge of the table, and his left ear facing down.

"Brother Hongzhong, look straight ahead of yourself."

"Sunrise me, I'm dizzy."

"Halo is normal, don't worry, I have never missed this reset method."

"Then you, how many people have you cured?"

"Congratulations, you are the first."

Li Ang calmly observed Yong Hongzhong lying on his back until his dizziness and nystagmus disappeared.

Then turn Yong Hongzhong's head 45 degrees to the right, and observe for 1 minute until the dizziness and nystagmus disappear.

"The last step, turn the head and torso to the right, yes, lie on your side."

Li Ang asked Yong Hongzhong to lie on his right side, and kept the position for a minute, and finally helped Yong Hongzhong up, "Now, sit up and stay still, concentrate and calm down."

Yong Hongzhong closed his eyes and sat still. It wasn't until 5 minutes later that Li Ang asked him to open his eyes, "Okay, it's done."

Yong Hongzhong stammered, "Is this all right?"

"Didn't you get dizzy when you lowered your head before?"

Li Ang said calmly, "Try now."

With the help of his close old servant, Yong Hongzhong cautiously got off the table,

Under the gazes of everyone around him, he slowly bent down and lowered his head, and said in shock, "No, I'm not dizzy."

"Huh—"

"You can cure a disease just by turning your head? Is there such a thing?"

"incredible"

Song Shaoyuan stood proudly beside Li Ang while listening to the noisy voices around him.

Ji Linlang and the other students from Kuangzhou raised their mouths slightly, revealing a proud smile.

Qiu Feng, the daughter of the imperial physician, pursed her lips tightly, nodding her head in admiration, but a trace of doubt, stubbornness and unwillingness flashed in her eyes.

"Thank you, Brother Risheng."

Yong Hongzhong excitedly thanked Li Ang, Li Ang waved his hand, and said casually, "They are all classmates, don't care."

"No, no, the gentleman has kindness to repay."

Yong Hongzhong couldn't help but take off a piece of pure white jade pendant carved in the shape of a fish from his waist, forced it into Li Ang's hand, and patted the back of Li Ang's hand gratefully.

"Brother Hongzhong is very polite."

Li Ang showed an embarrassed but polite business smile, his ears keenly caught the chubby student in the crowd muttering to himself, "Wow, Khotan Nephrite"

Khotan Nephrite?Is it worth it?
Li Ang was thinking about the value of the gift money, Yong Hongzhong paused for a while, as if he had just remembered it, turned around, and respectfully said to the girl in Chinese clothes on the other side of the crowd: "Also, I also thank Dr. Qiu and He Le. Lord An."

"What county master, call me cousin directly."

The girl in Chinese clothes, known as the Princess of Le'an, gave Yong Hongzhong a gentle and friendly smile, and her gaze accurately captured the eyes of everyone present.
And, Li Ang's strange gaze.
