"Doctor Yan, the truth is, let me tell you!"

Yang Xuan came to the bed and reached out to tidy up the messy hair for the woman on the bed.

"Doctor Yan, that's what it is..."

"My sister Yang Ting suddenly started talking nonsense three days ago, sometimes crying and sometimes laughing, and just saying something messy."

"And drooling..."

Yang Xuan pulled out a few tissues from the cardboard box on the bedside table, wiped the saliva at the corner of her mouth, and then said, "Sometimes, she would scream and jump excitedly."

"We were afraid that she would hurt herself, so we had to tie her up."

Yan Feifan asked coldly: "It's been three days since the illness, why are she still tied up at home and not sent to the hospital?"

Yang Xuan bit her lips and said with shame: "This is my parents and I are selfish."

"Doctor Yan, my boyfriend and I are scheduled for May Day. If they know my sister is like this..."

"They will definitely worry that I may also..."

She paused for a moment and said with a pleading look: "Doctor Yan, please show your sister and prescribe some medicines that can be kept normal for the time being after she takes it."

"We are going to take her to a mental hospital outside the province for treatment."

Hearing this, Yan Feifan didn't know what to say.

Worried that it would ruin his marriage, he actually imprisoned his sick sister at home.

Such a sister?

He couldn't help but look back at the middle-aged couple.

The two of them dodged their eyes and did not dare to look at Yan Feifan at all.

Yan Feifan was secretly disappointed and shook his head.

Only with such parents can there be such a sister...

He came to the bed, looked at his cheeks carefully, his eyes wandered, and his mouth was still muttering, and asked, "Have you given her medicine?"

Yang Xuan nodded and said timidly: "I have given her drugs like calm, but they have not done anything."

"Doctor Yan, isn't it any way to do it?"

Yan Feifan couldn't help but snorted coldly, then resisted disgust, and asked, "Do you have a genetic history of mental illness?"

After asking this, Yan Feifan immediately noticed that there was a hesitation and hesitation on Yang Xuan's face.

He immediately raised his voice, "Is there any?"

Yang Xuan bit her teeth and nodded and said, "Yes, my grandma has schizophrenia and is still receiving treatment in a mental hospital in Lin Province."

Yan Feifan knew it in his heart.

The genetic probability of this mental illness is quite high.

Studies have shown that the incidence rate of relatives of schizophrenia ranges from 4.3% to 16.4%, which is far higher than the incidence rate of 1% in the general population in my country.

However, although Yang Ting in front of her looks like a mental attack, as a rigorous doctor, Yan Feifan needs to have a check before he can make his final judgment.

He reached out and touched Yang Ting's forehead.

Yan Feifan immediately realized that her forehead was a little hot and her body temperature should be between 38.5 and 39 degrees.

He looked at Yang Xuan and asked with a serious look on his face: "Did your sister have a fever before it started?"

"Are the fever symptoms that only occur after the onset of the disease?"

Seeing that Yan Feifan asked seriously, Yang Xuan did not dare to answer casually. She thought about it seriously and said, "Doctor Yan, I really don't know."

"At that time, when I got home, I found something was wrong with my sister."

Yang Xuan looked at her parents and asked, "Do you know?"

The Yang family's parents looked at each other.

Yang's father said, "I really don't know this. That night, Tingting was very noisy and couldn't catch it at first sight and lifted the quilt."

"Maybe it was that night, she caught a cold."

At this time, Cai Yuanheng asked with concern: "Brother Yan, is this fever crucial before or after the onset of the disease?"

Yan Feifan nodded and said, "The body's fever is a warning from the body and a harbinger of many diseases."

"If her body started to have a fever before she started to develop an illness, then her current symptoms would be certainly likely, not a mental attack, but other causes."

"What other reasons?" Yang Xuan asked anxiously.

Yan Feifan didn't want to pay attention to her, a selfish person, and said perfunctorily: "There are several possibilities."

He opened the diagnosis box, took out the stethoscope and flashlight, and took out a pair of rubber gloves and put them on.

"I'm standing to do a full body examination on the patient."

"This process will touch the patient's body and even contact with very private parts."

Yan Feifan looked at Yang Ting's parents for consultation, "You..."

Yang's father understood and hurriedly replied: "Doctor Yan, you are a doctor, you can check it casually, we don't mind."

At Yan Feifan's request, Cai Yuanheng and Yang's father left the room, and Yang Xuan and her mother stayed.

Yan Feifan first listened to the patient's heartbeat, lung sound and intestinal sound with a stethoscope, and found that the patient's heartbeat was as high as 13, but he didn't hear any noise, and the lung sound and intestinal sound were also normal.

Next, Yan Feifan started with the patient's head and facial features.

Check whether there are any trauma in the brain, traces of insect bites or parasites, the pupil's reaction to light, the oral and tongue coating, and whether there is inflammation in the ear holes, etc.

No obvious abnormalities were found on the head and facial features, and Yan Feifan asked Yang Xuan to take off the patient's pajamas.

He checked the patient with his naked eyes and there were no biting marks or external injuries on the patient's body, and then he started to check.

Yan Feifan touched the patient's neck, then pressed and touched the patient's arms, chest and ribs along the collarbone.

Of course, Yan Feifan did not let the check on the pair on his chest.

After crossing his navel, his hand pressed on the patient's lower abdomen...

When Yan Feifan pressed the patient's lower left abdomen and moved to other parts, the touch from his hands suddenly made him feel uncomfortable and inconsistent.

This is more like a psychological feeling, the sixth sense.

Is there a problem here?

Yan Feifan concentrated and held his breath, returned to that part of his palm, increased his strength, and tapped, touched and pressed again, and felt more detailed in the abdominal area that made him feel awkward.

Yang Xuan and her mother also noticed that Yan Feifan seemed to have noticed and couldn't help but hold their breath...

After several strokes, a rough projection image of the belly gradually took shape in Yan Feifan's mind.

He finally found the reason why he felt abnormal.

Yan Feifan finished the remaining examination, covered the patient with a quilt, and stood up to look at Yang Xuan and her mother.

"Yang Ting has a high probability that a mass of two to three centimeters in diameter has grown on her left ovary."

"Tumor?"

"cancer?"

Hearing the mother and daughter's response, Yan Feifan said lightly: "I'm not sure yet. You need to send Yang Ting to the hospital immediately for confirmation and examination."

"besides……"

Yan Feifan further added: "If this lump is confirmed, then Yang Ting's current symptoms may be caused by this lump."

Yang Xuan asked in disbelief: "Doctor Yan, can tumors cause symptoms similar to mental illness?"

Yan Feifan nodded and introduced: "This disease is called autoimmune encephalitis."

"When the human body is infected with a virus or has a tumor, the human immune system will produce antibodies that poison invade viruses or tumors."

"However, this immune antibody sometimes does not distinguish between enemies and us."

"It sometimes attacks our own healthy central nervous system or brain tissue, causing neurological and mental disorders."

"Therefore, Yang Ting, a psychotic attack-like symptoms appear."

After hearing Yan Feifan's words, Yang Xuan looked at her sister whose saliva was flowing out of the bed, and then looked at Yan Feifan.

"Doctor Yan, my sister has this. How likely is it that you are immune to encephalitis?"

Before Yan Feifan could respond, Yang Xuan suddenly had a little emotional collapse and shed tears in a sudden burst of tears.

"Doctor Yan, I have nightmares every day these two days, afraid that one day, I will be the same as my sister."

She wiped her eyes and continued, "Doctor Yan, I would rather get cancer than get crazy," she said.

Yan Feifan sighed secretly and said, "I can't guarantee that your sister must have autoimmune encephalitis."

"I can only say that there is a chance, and it's quite high."

"Hurry up and send your sister to the hospital..."
