That's not all, as the sky gradually brightened, the people in the student dormitory building and the faculty dormitory building began to get up, coughing, walking, laughing and scolding, the sound of dressing, the sound of dreaming, the sound of running water, the sound of gargling, the sound of urinating, the sound of reading, no matter what the sound, as long as any sound found in these two buildings came to Zhu Daidong's ears, making him feel uncomfortable.

I have to go to the doctor, Zhu Daidong thought silently. He didn't even think about going to the hospital because of his brain injury, but now he has made up his mind that he must go to the hospital, because he suspects that he is insane, and if he doesn't see a doctor, he will go crazy if he doesn't go crazy.

Zhu Daidong had classes in three or four classes in the morning, and it was enough to go to the health center to see a doctor. When he returned to the dormitory, he saw that Long Yiping was indeed there to correct his homework, and his heart was even more nervous. After quickly taking a change of clothes and a small bucket, he fled out of the dormitory.

"What nerves?"

After going out, Zhu Daidong heard Long Yiping snort softly. This sentence made Zhu Daidong's feet feel like a wind, and even Long Yiping could see that he was abnormal, which was miserable.

At this time, Zhu Daidong had a lot of thoughts, where could he think that it was precisely because of his abnormal behavior just now that Long Yiping had some words. If he had been as usual, he had prepared all his belongings slowly and then went out, would Long Yiping have said this?

When I got to the bathroom, I found that I was in a hurry and forgot to bring soap. At this time, Zhu Daidong was not in the mood to go back to get it again, so he took a towel and wiped it casually under the faucet, as if he had finished taking a bath. After washing, he didn't wash the changed clothes as usual, stuffed the dirty clothes into the bucket, returned to the dormitory and threw them under the bed, changed his shoes, took some money and left the school.

Shuling Middle School is in the northern part of the township, while the township health center is in the south. Walking out of school, along the way, Zhu Daidong's ears couldn't be quiet. Especially after walking to the street, although there are few pedestrians, Zhu Daidong is like going to a vegetable market. All kinds of cacophony of voices poured into his ears whether he wanted to or not. When passing by the dormitory building of the township government, he heard the sound of humming, which made him blush and run over as if he had fled.

The township health center did not have a special neurology department, so Zhu Daidong had to hang up an internal medicine department. The hospital was very quiet, but this was only for others, in Zhu Daidong's ears, he could hear the sound of drips hanging in the upstairs ward, although he didn't go up to see it in person, but the drops of potion that fell down seemed to be attached to his ears, which made him feel very panicked.

"What's wrong with you?" There was a doctor in his fifties sitting in the internal medicine clinic, and when he saw Zhu Daidong walking in, his eyes scanned his whole body. But under the "look", the doctor was a little puzzled, the young man who came in, his face was ruddy, full of energy, although the tip of his nose was sweating, but it was obviously nervous, so his condition had nothing to do.

"Doctor, I suspect I'm nervous." Zhu Daidong said truthfully.

"Insanity? Young man, you can't just say that. The doctor laughed and said, "Since you say that you are insane, what have you found?" ”

"I'm now very sensitive to the sounds of the outside world, and I can hear them whenever there's a stir, and my ears are filled with all kinds of sounds." Zhu Daidong said truthfully.

"Hehe, this doesn't have to be insanity, young man, don't panic, I'll listen to your heart rate." The doctor said with a smile, and he tried his best to calm down Zhu Daidong in a calm tone.

"But I ......"

"Don't talk yet, let me listen. Well, my heart is strong, and there's no murmur anywhere else, boy, have you been overtired lately or haven't rested well? The condition you are talking about should be tinnitus. The doctor checked Zhu Daidong's cardiopulmonary function very responsibly, and found that he was normal, and when talking, the other party was organized and spoke clearly, which was not a symptom of insanity at all.

Tinnitus refers to the abnormal sound sensation produced by people without any external stimulus, which is often a precursor to deafness and is caused by auditory disorders. However, other factors, such as excessive fatigue and poor rest, may not be accompanied by deafness or vertigo.

Whereas, insanity refers to the confusion of a person's mind and thinking, and the loss of normality. Zhu Daidong didn't have these two points, how could this doctor think that he was insane.

"I've been sleeping very little lately, and ......, doctor, does this have anything to do with drinking?" Zhu Daidong did not argue with the doctor anymore, in terms of teaching and educating people, this doctor could not compare with himself, but in terms of treating diseases and saving people, he could not be compared with him.

"That's right, young people should maintain enough sleep time, and drink less alcohol, a small glass a day is conducive to promoting blood circulation, but drinking more will hurt the stomach and liver." The doctor felt that the cause of Zhu Daidong had been found, and alcoholism, coupled with lack of sleep, could cause tinnitus.

"But ...... my ears?"

"It's okay, go back and rest more, eat fresh vegetables, remember, don't drink too much, you'll be back in a few days." The doctor advised.

"Don't you need some medicine?" Zhu Daidong asked stupidly.

"If you want to prescribe medicine, you can also send some vitamins and glucose to you, vitamins are to supplement your nutrition, glucose is used for hangover, if you drink too much wine in the future, remember to drink glucose after drinking, otherwise your tinnitus will recur."

Glucose is rich in tartaric acid, which can interact with ethanol in wine to form esters, reduce the concentration of ethanol in the body, and achieve the purpose of hangover.

"Thank you, doctor."

In the pharmacy, Zhu Daidong asked the nurse for some medical cotton, and after leaving the health center, he divided the cotton into two balls and stuffed it into his ears, and the noise suddenly became much less. Looking at the vitamins and glucose in his hands, Zhu Daidong knew that he had found the real "medicine".

After returning to school, Zhu Daidong felt much better, although he would still hear some voices from time to time that others couldn't hear and he didn't want to hear, but the feeling of pouring into his ears with the original various sounds was much better. He also experimented and quietly took out the cotton balls, but the sound of recitation from the school building almost didn't make him deaf. The effect is like a person standing next to a tweeter.

After returning to the dormitory, Zhu Daidong improved the cotton ball, and now the cotton ball in his ears is too big for others to see. If he is found by the school and has nothing to do with plugging his ears, I am afraid that he is not insane, but will also be rumored to be insane. After the improvement, the cotton ball has become smaller, and as long as you don't look carefully at the ear, no one will notice it.
