Working together without a plan

"I just happened to encounter kidney stones and ureter stones. The real problem isn't here, but the patient's physical condition has deteriorated drastically in the past few days, especially in the few hours after he arrived at the hospital. " Zheng Ren gave a simple explanation and then returned to the topic. He asked,""Has she been eating anything strange recently? Do you have any bleeding gums or frequent periods?"

A girl said,"doctor, we were resting in the office a few days ago. We were eating apples. I saw that her gums were bleeding." The Apple is covered in blood, it's scary. "

Gums bleeding. This was a hint.

"One day ago?"

"No, I remember it's been about a week."

Zheng Ren was stunned.

A week?

Judging from the speed of the disease's progress, one day was more than enough.
