One night last month, my college roommate suddenly had a terrible stomachache. We're all scared. She was pale and sweaty. She can't drink water, and she vomits. We called several classmates, told the teacher and sent her to the affiliated hospital of Hebei University of Engineering for treatment overnight. She used to have gallstones, because she didn't commit them for several years and didn't care. She used to take medicine for treatment, but she hasn't taken medicine in recent years. I didn't expect to get sick at night. Doctors from the Affiliated Hospital of Hebei University of Engineering examined her and said that her condition was estimated to require surgery to remove stones. Fortunately, the stone is not big, so I took a detailed picture.
