Many diseases will cause patients to develop symptoms of lumbar pain when the weather changes, for example, myofasciitis of the lumbar region, lumbar muscle strain, lumbar intervertebral disc herniation of some patients, when encountering a change in the weather will develop symptoms of lumbar pain. Analyzing from the theory of Chinese medicine, once the weather change causes wind, cold and dampness to invade the body, it will lead to stagnation of qi and blood stasis in the lumbar region, the meridians and collaterals are blocked, and if they are not blocked, it will cause pain, thus producing the symptom of lumbar pain. In terms of the etiology and pathogenesis of Western medicine, some patients are very sensitive to weather changes, especially under the stimulation of cold and humidity, which can make the lumbar muscles spasm, leading to adhesions and hyperplasia in the lumbar tissues, resulting in aseptic inflammation, and under the stimulation of the inflammatory factor, the symptoms of lumbar pain will occur, so patients should pay attention to keep warm and add clothes in time to avoid getting cold when the weather changes.
