The patient pointed to the back of her right thumb, where she could see a large area covered with dense red, pimple-like blisters; in some places, the skin had already cracked.
The skin is the first line of defense protecting the human body.
At the same time, the skin is also the most magical organ of the human body. Its marvel is even greater than that of the human brain.
To date, there are 713 unsolved mysteries about human skin that scientists have yet to decipher.
For instance, when someone quietly approaches us from behind, we may feel a tingling in the scalp. Even though no sound is heard yet, the skin can sense someone approaching before our ears do.
Moreover, when we close our eyes and use our hands to touch different objects, we can directly know the temperature, material, hardness, and weight of these objects through the tactile feedback of the skin.
...
Li Jingsheng always harbored a sense of fear when treating skin diseases for patients.
Because most skin diseases have a rather strong infectious nature.
He refrained from touching the patient’s hand.
He just focused intently on it.
Based on his experience, this was a typical case of tinea manus, a fungal infection.
"Does your left hand itch as well?"
Li Jingsheng noticed that in the brief time the patient was seated there, he had already scratched the back of his left thumb twice.
"This hand seems to start developing red particles too, and it’s very itchy."
The patient spoke while scratching his left hand with his right.
At this moment, his right hand also started itching, but he didn’t dare to scratch hard. Because once tinea manus progresses to blisters and cracks, the skin lesions become very severe. Scratching at this stage would cause excruciating pain.
"Have you used any medication?"
Li Jingsheng asked.
"Initially, an elder in my family told me to soak my hands in very hot water to scald the germs to death. After trying, I found it not only unhelpful but also made the affected area grow larger. Even the side of my ring finger developed some particles and began to itch."
Many people, when suffering from athlete’s foot, believe that scalding with hot water can cure it.
Such folk remedies are truly harmful.
It’s unknown who started spreading this.
The infected skin area, once scalded with hot water, gets stimulated, worsening the tinea manus instead.
"Haven’t you bought any medication to treat it?"
"I bought a tube of ’King of Dermatitis’ for 15 yuan from the pharmacy. It worked initially, with the skin oozing a clear liquid. But after a few days, it recurred. After several applications, its effect seemed to diminish, and now my girlfriend won’t even let me touch her."
The man looks about twenty-seven or twenty-eight.
He could endure the other troubles brought by tinea manus, but he definitely couldn’t bear his girlfriend forbidding contact.
"It appears to be tinea manus, a common condition. It is contagious."
Li Jingsheng didn’t continue, only informing the patient of its dangers.
"I’ve also heard it’s contagious; my left hand seems to be infected already. Do you have any solution for this?"
"Certainly, there are solutions; tinea manus isn’t hard to treat."
With just a few words from Li Jingsheng, the man immediately saw hope, and his previously tense expression instantly relaxed considerably.
It was evident that tinea manus had caused him significant mental stress.
"I heard your medical skills are excellent, so I specially came for your help. Dr. Li, please think of a way to help me."
Instinctively, the man wanted to grab Li Jingsheng’s hand to plead with him.
