For the causes of squatting lumbar pain, the specific reasons are as follows: First, severe lumbar strain: the patient will have restricted lumbar forward flexion activities, when squatting, there will be obvious lumbar pain, the lumbar muscles will have soreness and weakness symptoms, and the lumbar spine range of motion will be significantly reduced. Through local massage, massage and hot compress, the clinical symptoms can be relieved quickly. In ordinary life, strengthening the exercise of the lumbar back muscles can prevent lumbar muscle strain. Second, lumbar disc herniation: if the patient does squatting posture, it will increase the pressure of the intervertebral disc, leading to further protrusion of the nucleus pulposus to stimulate the nerves, causing painful symptoms in the lumbar area, and at the same time, it will be released to the buttocks and lower limbs, and the range of motion of the lumbar vertebrae will be restricted, and the degree and location of the lumbar disc herniation will be found through MRI. Early treatment can lead to significant relief of clinical symptoms, and patients should also pay attention to strengthening lumbar back muscle training to protect the lumbar spine in ordinary life.
