Lumbar muscle strain is a particularly common disease, such as strenuous exercise or long periods of heavy physical labor. For instance, farmers bending over, farming, hoeing, cutting grass, fertilizing, and spraying pesticides are all activities closely related to the movement of the lumbar muscles. The human body's muscles engage in 80% of activities, and their involvement in lumbar muscle strain is very common. It mainly manifests as swinging hammers, digging tree pits, bending over to lift heavy objects, and carrying heavy weights. Subsequently, pain and discomfort in the lumbar region occur. The next morning, upon waking, the symptoms may become more apparent. The lumbar area may feel stiff, akin to a plank, making getting out of bed difficult. Through physical examination and radiographic imaging, such as CT scans of the lumbar spine, the condition can generally be identified and confirmed. In such cases, strict bed rest is required, generally for at least ten days, during which symptoms gradually alleviate. During this period, treatments such as traction, physiotherapy, massage, and heating can help alleviate the symptoms. If necessary, blood-activating and pain-relieving medications may be taken. The condition is treatable, but it is advisable to avoid prolonged sitting in the future. When engaging in heavy labor, it is better to restrict the lumbar region by wearing a lumbar belt or engaging in lighter physical activities that do not overly exert the lumbar area. Regular care for the lumbar region is essential. Once there is damage to the lumbar region, recurrent episodes can affect the quality of normal life and work.
