Pain in the lumbar region is particularly common in clinical practice. Pain in the lumbar region occurs when the patient is sitting, but not when standing. Basically, it is due to the inattentive sitting posture in daily life and the stimulation of wind and cold in the lumbar region, which causes muscle fascia spasm and congestion and edema, resulting in localized pain due to sterile inflammation. Moreover, the force on the lumbar region is greater when the patient sits than when he stands, which will certainly trigger the emergence of lumbar pain. When the patient is standing, the lumbar muscles are relaxed and not bent, so the lumbar pain is lighter or even no pain occurs. Patients are advised to pay attention to the correct sitting and standing posture and to keep their lumbar area warm.
