"Can you, can you cure?"

Yong Hongzhong asked in surprise and joy. During this period, he was tortured by the nameless strange disease that was dizzy when squatting down. In order not to make people laugh, he deliberately kept standing and sitting.

But every night, when you lie down in bed and sleep, you may still feel nauseous or even vomit.

Li Ang nodded calmly, "Yes."

"Doctor Li, what disease does my husband have?"

Yong Hongzhong's personal servant was asked respectfully, and his name changed from "Little Langjun" to "Doctor".

Benign paroxysmal positional vertigo.

Or, otolithiasis.

Li Ang silently recited the answer in his heart.

As vertebrates, humans can balance themselves during exercise mainly because they have organs in their ears that regulate body balance.

The organ is composed of three tubes and two capsules. The three tubes refer to the front semicircular canal, the back semicircular canal, and the horizontal semicircular canal, which is responsible for feeling the angle of the head.

The two sacs refer to the balloon and the elliptical sac.

In the structure of the two capsules, some calcium carbonate salts are crystallized, like small stones or chalk powder, so they are also called otoliths.

Otoliths are usually fixed in both capsules, assisting the two capsules to sense the acceleration of the head and transmit position signals to the central nervous system through the nerves.

It is precisely because of three tubes and two capsules that humans can "sensate" their body's balance and gravity state, and will not fall flat or feel dizzy.

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

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

Otolithia is more common in middle-aged people and slightly more in women. The causes may be head trauma, strenuous exercise, long-term staying up late, or middle and inner ear surgery, etc.

Just now, Li Ang first ruled out the possibility of Meniere's disease and migraine through physical examinations and inquiries.

Through the Dix-Hallpike displacement test, that is, holding Yong Hongzhong's head, he guided him to lie back and quickly, actively let the otolith touch the semicircular canal, inducing a dizzy reaction,

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

(Posterior semicircular canal otolithia, that is, otolithia runs to the posterior semicircular canal position. When this happens, the Dix-Hallpike displacement test will only cause nystagmus when the affected side turns and lying on the side, and there will be no nystagmus on the healthy side. And both sides of the anterior semicircular canal otolithia will be nystagmus)

Of course, these processes are not easy to tell everyone in front of you.

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

This is a bit incredible.

You should know that in the memory of another world, doctors discovered otolithia in 1921, but it was not until 1980 that a doctor named John April realized that the cause of otolithia was otolithia and used reduction techniques to treat patients with otolithia.

In the middle, doctors cure otolithia by cutting off the vestibular ganglia - the consequence is that the patient will lose hearing and balance.

Moreover, even after John April proposed that the reduction method could be used to cure otolithia, his research results were not widely recognized. Instead, they were excluded, ridiculed, and even legal accusations of illegal practice of medicine.

Li Ang's mind changed rapidly. It was difficult for him to convince the people in front of him, telling them that the reason why people can feel the changes in gravity and position is because there are stones in their ears.

Even if you convince, there is no evidence. Instead, you will be suspected of something shocking and other things that you secretly do.

Yu's medical level is relatively backward than architecture, materials science, astronomy, etc.

On the one hand, this situation 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 anatomy and study of human corpses was a taboo in the former Sui Dynasty and the Yu Dynasty - this is almost a magical act.

Li Ang still remembers Pu Liuxuan's advice. He must first be admitted to the academy to have social status, the foundation of his life, the right to speak and influence.

Doctors must first protect themselves before they can protect the patients.

In the blink of an eye, Li Ang weaved a set of rhetoric that could be accepted by people around him, and said without changing his face and his heart was still beating: "Although there are many diseases of dizziness, it is nothing more than both the deficiency and the reality.

Those with deficiency are mostly deficiency of qi and blood, insufficient marrow and loss of nourishment in the clear orifice.

Brother Hongzhong has been studying too hard recently and has used too much energy. In addition, his body is weak and his qi and blood supply are insufficient, which leads to dizziness."

"I see."

Song Shaoyuan and others showed an expression of "Oh, so that's how it is, well, I understand completely now", and nodded.

Qiu Feng felt something was wrong and frowned and looked at Li Ang, wanting to speak but stopping.

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

Yong Hongzhong's personal servant asked respectfully,

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

On the other hand, it is necessary to reset manually and assist.

That is, rotate the mind, let the qi and blood in the heart surge to the head, and unblock the qi mechanism in the head.

Only by combining the two methods can we completely heal.

Come on, Brother Hongzhong, sit back again.”

Li Ang asked Yong Hongzhong to sit back on the table, hold his head again, and turn his head to the left 45 degrees of the affected ear.

Then pull the head and guide Yong Hongzhong to lie down, extending his head slightly out of the edge of the table, and the left side of the affected ear faces down.

"Brother Hongzhong, look directly in front of you."

"I'm dizzy when I'm rising."

"It's normal to be dizzy, don't worry, I've never missed this reset method."

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

"Congratulations, it's the first one."

Li Ang observed Yong Hongzhong lying on his back with a calm expression until his dizziness and nystagmus disappeared.

Turn Yong Hongzhong's head again, turn it to the right 45 degrees, and observe it for one minute until the dizziness and nystagmus disappear.

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

Li Ang asked Yong Hongzhong to lie to the right side, keep his posture for a minute, and finally helped Yong Hongzhong up, "Now, sit up and don't move, concentrate and calm down."

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

Yong Hongzhong stammered and said, "Is that good?"

"Didn't you feel dizzy when you lower your head?"

Li Ang said calmly: "Try again now."

With the help of his personal servant, Yong Hongzhong carefully got off the table.

As everyone around him looked at him, he slowly bent down and lowered his head, and said in shock: "No, don't you faint."

"Wow—"

"Can the disease be cured by just turning your head? Is there such a thing?"

“Incredible….”

Song Shaoyuan stood proudly next to Li Ang as he listened to the noisy voices around him.

Ji Linlang and other students in Benzhou had slightly raised their mouths, revealing a proud smile.

The daughter of the imperial doctor Qiu Feng, pursed her lips tightly and nodded in her praise. She also had a trace of doubt, stubbornness and unwillingness in her eyes.

"Thank you, thank you Brother Risheng."

Yong Hongzhong bowed to Li Ang excitedly and thanked him. Li Ang waved his hand and said casually: "All classmates, don't care."

"No, no, a gentleman needs to repay his kindness."

Yong Hongzhong took off a white and flawless jade pendant carved into the shape of a fish from his waist without saying a word, forced it into Li Ang’s hand, and patted it on the back of Li Ang’s hand with gratitude.

"Brother Hongzhong, please be polite."

Li Ang showed an awkward and polite business smile, and his ears keenly captured the slightly fat student in the crowd muttering to himself, "Wow, Khotan soft jade..."

Khotan nephrite? Is it valuable?

Li Ang thought about the value of the gift money casually. Yong Hongzhong paused for a while, as if he had just remembered it, turned around and respectfully said to the gorgeous girl in the other side of the crowd: "Okay, thank Dr. Qiu and Princess He Anle."

"What princess, just call me cousin."

The gorgeous girl, known as Princess Anle, smiled at Yong Hongzhong gently and friendlyly, and her eyes accurately captured the eyes of everyone present.

And, Li Ang’s strange gaze.
