101: Finally found the root of the problem

Miss He Wan wasn't too surprised to hear it was a nerve problem.

After all, for an Old lady, nerves tend to be more sensitive and weak as she gets older.

Qin Jiang continued to ask, "Old lady, do you feel uncomfortable anywhere else normally?"

The Old lady still said with a straight face, "Headache, numb mouth, can't sleep well."

Good heavens, you only know that one sentence, don't you?

Knowing that he couldn't get anything out of the Old lady, Qin Jiang could only turn his gaze to Miss He Wan.

Miss He Wan added from the side, "My grandma's symptoms started a year ago."

"One day, she suddenly said her mouth felt very numb, everything she ate felt numb, and then as time went on, my grandma started having headaches and insomnia."

"We also consulted other doctors, but they couldn't figure out what was wrong with my grandma."

After hearing Miss He Wan, Qin Jiang already had a general judgment in his mind.

The first characteristic of nerve problems is numbness.

Just like many hemiplegic patients, many of them don't become paralyzed all at once; instead, a part of their body first feels numb, and then the condition gradually worsens.

The Old lady at this moment was somewhat similar to this situation.

"Old lady, close your eyes. I'll give you Acupuncture."

Although the Old lady didn't understand why she had to close her eyes for Acupuncture, she still obediently complied.

Qin Jiang took out silver needles, sterilized them, and then directly inserted them into the Old lady's head.

After one needle went in, the Old lady's right index finger trembled uncontrollably.

Seeing this scene, some netizens sent bullet comments asking.

"What is he doing? Why is this Old lady's index finger trembling?"

"Dr. Qin should be using Acupuncture to stimulate Acupuncture points to determine which meridian is problematic. This is too amazing; I've only seen this method in ancient texts before."

According to Chinese medicine, there are many meridians in the human body, and these meridians govern the internal organs, limbs, and bones.

So, as long as you can fully understand the function of each meridian and each Acupuncture point, you can use this method of Acupuncture to determine which meridian has been damaged.

To put it simply, meridians are like electrical wires, and parts of the human body like fingers and toes are like light bulbs connected to these wires.

Acupuncture is like electrifying the wire that controls the index finger.

If the index finger reacts, it means the light is on, indicating that this meridian is fine.

Conversely, it means there must be a problem with this meridian.

Using this method, Qin Jiang inserted more than forty needles into the Old lady's head, but found that the Old lady's body was very healthy, all her meridians were functioning normally, and were not subjected to any interference.

This made Qin Jiang a little puzzled.

If the Old lady's meridians were fine, then her body should be very healthy, so why did her mouth feel numb?

As soon as Qin Jiang showed this expression, Miss He Wan immediately understood.

She somewhat awkwardly helped Qin Jiang out of the situation.

"It's okay, Dr. Qin, other doctors haven't cured my grandma's illness either, so you don't need to be too discouraged."

"I will still continue to support you and watch your live stream."

Qin Jiang: ...

This little girl is a bit impatient.

He hadn't even reached a conclusion yet, why was she in such a hurry?

Qin Jiang said in a deep voice, "The Old lady's illness is indeed a bit tricky. Has she had any major surgeries these past few years? The kind that involves an operation."

Miss He Wan shook her head.

"No, Grandma has always been in good health and rarely gets sick."

"If I had to say, does tooth extraction surgery count?"

"My grandma broke two teeth a year ago while biting walnuts, so my dad took her to get two false teeth replaced."

As soon as Miss He Wan said this, the netizens in the live stream burst into laughter.

"This Old lady is so funny, biting walnuts directly with her teeth, of course, she'd break her teeth."

"My dad is like that too; he uses his teeth as a bottle opener for beer, and now he can't even afford to get his teeth filled."

"Old people are all like this, unlike me, I just crush walnuts with my hands."

"No, don't you know there are special tools for cracking walnuts? Are you all cavemen?"

The netizens' attention was all on how to use teeth.

But Qin Jiang was attracted by an important piece of information.

"You just said your grandma got her teeth replaced a year ago too?"

"Was it before she got her teeth replaced that your grandma felt her mouth numb, or after she got her teeth replaced?"

Miss He Wan thought for a moment and then said, "It was after she got her teeth replaced."

Qin Jiang immediately thought of something and asked the Old lady to open her mouth again.

This time, Qin Jiang saw clearly, and finally had a deduction.

"Alright, I know how to treat your grandma's illness. Give me three hundred yuan, scan the code to pay."

As a loyal fan, Miss He Wan knew that as long as she scanned the code to pay, it was a sure thing.

Miss He Wan scanned the code to pay without hesitation, and a notification sound immediately rang in Qin Jiang's mind.

Ding.

[Detected that the host was blunt with the patient, revealing the patient's hidden illness, which greatly helped the patient. Task completed]

[Congratulations to the host for receiving the reward: God-level White Rabbit Creamy Candy!]

Hmm?

You're starting again, aren't you?

Damn system, you're stirring things up again!

Qin Jiang's face was grim.

It was one thing when you gave me a feather duster before, but what's the meaning of giving me a White Rabbit Creamy Candy this time?

Can candy cure diseases?

"Dr. Qin, what's wrong? There shouldn't be any problem with my grandma's illness, right?"

Seeing Qin Jiang's face suddenly turn so grim, Miss He Wan was also startled.

Realizing that his state was affecting the patient, Qin Jiang took a deep breath, adjusted his mood, and said, "It's nothing, I just suddenly remembered some unpleasant things."

"The Old lady's illness is actually very easy to treat; it's just a problem with her teeth."

"Huh?"

Miss He Wan couldn't understand.

Qin Jiang explained, "One of the Old lady's teeth is a gold tooth, and one is an aluminum tooth, right?"

Miss He Wan nodded.

"Originally, we planned to install two gold teeth, but our family's financial situation wasn't particularly good, so at that time, we first installed an aluminum tooth for Grandma to make do."

"Yes, it's that 'making do' that caused the problem."

Qin Jiang continued to explain, "Gold teeth and aluminum teeth, due to their material, can be considered the positive and negative electrodes of a battery, and the Old lady's saliva is equivalent to the electrolyte."

"Simply put, as soon as these two teeth were installed, the Old lady's mouth was equivalent to a simple galvanic cell."

"This is also why the Old lady often feels her mouth is very numb; it's because the battery is discharging."

"And these currents in her mouth will also affect the Old lady's bioelectricity, which is why she experiences headaches and insomnia."

When Qin Jiang finished speaking, everyone was stunned.

It can be like this?

Installing a false tooth can turn it into a galvanic cell?
