Irregular metabolism and blood circulation can cause lumbar muscle strain. There are also some patients who live in an environment with low temperature or high humidity, which leads to lumbar muscle strain. When lumbar muscle strain occurs, it can be adjusted by external use of drugs such as Vivi (or "keeping in good health"), and physical therapy methods such as electromagnetism, ultrasound and infrared rays can also be used. Usually pay attention to avoid overwork, keep the correct standing and sitting posture every day, and exercise your waist properly after sitting for a long time to reduce pain.
