Previously, there was a 20-year-old girl who went to see a doctor and pointed to a muscle on the right side of her waist. After examination, it was found that unlike the symptom of shingles "lightly touching causes pain but pressing does not", she had pain when pressed, no redness or swelling. After consulting with her surgical attending physician, it was determined to be "aseptic inflammation of soft tissue."
The expert explained: "Long-term fatigue, coldness in the waist area, and exercise can all cause this condition. Your pants are too low and the belt is tied too tightly, just in the middle of a group of limb girdle muscles. It may be a condition caused by compression, or it may be due to coldness." He suggested that the girl should wear high-waisted, loose-fitting pants, and not have the belt too tight. He also gave her some drugs to improve microcirculation.
