Patient, female, 38 years old, was originally a farmer in the countryside, mainly engaged in farming, laundry, and cooking. After getting married and having children, she moved to the city with her husband at the age of 27 to find work.
As they only had a middle school education and no special skills, they could only engage in the simplest jobs.
Her husband worked at a construction site, and she washed dishes in a restaurant.
Afterward, she changed jobs several times, always washing dishes or serving as a waitress.
About two months ago, without any obvious inducements, the patient felt a soreness in the muscles of her left calf. The soreness was not intense, and it was particularly evident when she stood up after sitting or squatting for a long time.
Initially, she thought it was due to fatigue and did not pay much attention to it.
Less than a week later, the patient had difficulty walking when standing up, breaking a stack of dishes, which led her to decide to visit a doctor.
