Calcium deficiency does not directly cause lumbar strain, there may be more or less a correlation. Calcium deficiency in menopausal female comrades or elderly people can lead to further aggravation of osteoporosis, which can cause lumbar pain, and under the stimulation of this pain can induce lumbar muscle strain. Clinically, lumbar muscle strain is mostly seen in young and middle-aged people, mainly related to the nature of sedentary, standing, bending, strain and strain. After bed rest or symptomatic treatment such as hot compresses and physiotherapy, the lumbar pain caused by lumbar muscle strain can be significantly relieved. However, the lumbar pain caused by osteoporosis due to calcium deficiency has no way to relieve pain through the above treatment methods, or the above pain relief is not effective, and it needs to be treated for a long time through calcium supplements or strengthening physical exercise to have certain effect.
