I practiced medicine in ancient times

The patient was a young woman wearing a long green dress and a white veil on her face. She looked tired and seemed to be suffering from illness.

The girl was followed by a noble lady in her early forties. The lady had a noble temperament and when she looked at the girl, her brows revealed deep concern.

"Doctor Zhou, my daughter's old illness has recurred, and this time it seems to be more serious than before. Please take a look at her." Madam Liu glanced at Xu Qingyi and Bai Yan who were standing behind Doctor Zhou. She and her daughter were sitting on the stool opposite Doctor Zhou. Madam Liu said to Doctor Zhou with a somewhat unhappy expression.

"Oh, can you let our two apprentices take a look at the rash on Miss Liu's body first?

I will be able to prescribe the right medicine based on their descriptions. Miss Liu doesn't know medicine, so she will inevitably miss a lot of things when she tells you orally." Doctor Zhou asked Madam Liu.

Doctor Zhou seemed to be quite familiar with Miss Liu's chronic illness. It was an emergency, but it also healed quickly, and it would flare up from time to time, making it very difficult for Doctor Zhou to deal with.

Because Miss Liu was a girl, it was not convenient for him to check her symptoms. Based on Miss Liu's oral description, he would inevitably overlook many things and not have a more intuitive understanding of her condition, so it would be more difficult to treat her.

Xu Qingyi and Bai Yan happened to be here today. They both knew about medicine, so he asked them to check Miss Liu's symptoms first, hoping to find some clues that would allow him to better understand Miss Liu's condition and develop a more effective treatment plan.

"Why not? I don't know what the two young doctors' names are. I may have to trouble you in the future." Madam Liu nodded to her daughter.

"My surname is Xu and hers is Bai. Madam Liu and Miss Liu can just call us Xiao Xu and Xiao Bai." Xu Qingyi stepped forward and said with a smile.

"Thank you, Doctor Xu and Doctor Bai." At this time, Liu Ruyan stood up and nodded slightly to Xu Qingyi and Bai Yan.

"Miss Liu, please come this way." After Xu Qingyi returned the greeting, he directed Miss Liu to the compartment.

"Is this an eczema or an allergy?" When Xu Qingyi led Miss Liu to the clinic's cubicle, she narrowed her eyes slightly and could vaguely see red urticaria on her body through Miss Liu's clothes.

Miss Liu twisted and scratched the wheal uncomfortably, which looked very itchy and extremely uncomfortable.

"How do you know?" Miss Liu asked in surprise when she saw that the two women in front of her had not checked her condition yet and told them what her illness was.

“I can tell from your exposed skin, but I haven’t looked closely yet, so I can’t make a definitive conclusion.

Miss Liu, please show me your bare arms." Xu Qingyi said with a slight smile.

Xu Qingyi saw Miss Liu roll up her sleeves and expose her arms. She saw red wheals on her arms. She gently touched Miss Liu's skin and felt the slightly raised skin under the wheals and the slight burning sensation.

"This is an eczema." Xu Qingyi said affirmatively.

"This is an allergic reaction, which may be caused by certain foods, drugs or environmental factors. Is it an emergency? Does it occur often? What did you eat or come into contact with before the onset of the disease? Is it different from the past?" Xu Qingyi asked.

Addictive rash, which means allergy, is the name of a disease in Traditional Chinese Medicine. It is an itchy, allergic skin disease with red or pale wheals that appear from time to time. It is caused by the body's intolerance to certain substances.

It may be due to weak defense system, which allows wind-cold and wind-heat to invade the skin; or due to dampness and heat from the stomach and intestines accumulating in the skin; or due to insufficient Qi and blood, which causes internal wind; or due to internal injury of emotions, imbalance of Chong and Ren meridians, and insufficiency of the liver and kidneys, which causes wind evil to accumulate in the skin and cause the disease.

Just now, Xu Qingyi touched the wheal on Miss Liu's arm. The wheal was obviously bright red and swollen, and it could be preliminarily determined that it was a symptom of wind-heat invading the exterior.

“Yes, it’s an emergency. Every time it breaks out, it comes on suddenly and it’s very itchy.

It has been going on for three years, and most of the time it breaks out is in spring and summer. There seems to be nothing special about it that is different from the past. "Miss Liu frowned slightly, thinking about her diet and daily routine today, and she shook her head in distress.

She had also consulted Dr. Zhou many times over the years, and the doctor diagnosed her with eczema, but the cause of the disease was not found. So in the past three years, she suffered terribly and was very uncomfortable whenever the disease broke out.

"Apart from the arms, where else on the body are these wheals?" Xu Qingyi continued to ask.

Although eczema is not a serious disease, it is very stubborn and will cause great pain to the patient once it breaks out. Moreover, the causes of eczema are very complicated, and different patients may have different causes, making it very difficult to treat.

"Here and there, all over the body."

Xu Qingyi pondered for a while, and glanced at Miss Liu's shoulder. She found a white hair. The hair was short and light, and it was obvious that it was not her hair or other part of her body.

Xu Qingyi plucked the hair from Miss Liu, put it between her nose and sniffed it gently. A slightly sweet smell came, followed by a smell of urine.

This is a cat hair.

This means that Miss Liu’s rash is most likely caused by her allergy to cats.

After finding the cause of the disease, Xu Qingyi asked, "Miss Liu, do you have any pets at home? For example, a cat or something like that."

"Doctor Xu, how did you know? I do have a cat at home." Miss Liu asked in surprise when she heard this.

"Miss Liu, every time your eczema breaks out, is your cat present or do you touch it?" Xu Qingyi continued to ask.

"This cat was raised three years ago, and the rash has been occurring for three years. It seems that every time the rash attacks, Xiaobai is not only present at the scene, but sometimes he has even touched it." Miss Liu is also an understanding person. When she heard Xu Qingyi's question, she knew what was going on.

Then, her eyes lit up slightly as she looked at Xu Qingyi.

"That's right, your rash is related to cats.

In the future, as long as you don’t come into contact with cats, the rash will not occur again and the triggering factor will be isolated.

But I'll feel your pulse again." After Xu Qingyi found the cause of Miss Liu's eczema, he offered to feel Miss Liu's pulse.

Miss Liu did not look down on Xu Qingyi because of her young age. Just based on her ability to find the cause of her addiction rash for three years, she knew that Xu Qingyi's medical skills should not be underestimated.

Doctor Zhou was also famous in the county. He had been treating himself for three years. Although he was able to cure every attack of acute addictive rash, he still could not find the source of his illness.

From this, we can see that Xu Qingyi's medical skills are not weak.
