Total back cramps, mainly due to persistent muscle spasms and contractions in the back, resulting in the appearance of the symptoms. The common causes include the following: 1. Acute injuries and chronic strains, including strains after strenuous exercise, and long periods of high workload, resulting in fatigue injury to the muscles, can cause local pain and dysfunction, resulting in spasm, contraction, and cramping symptoms; 2. This can lead to frequent cramps; 3. The patient’s back is continuously cold, which leads to poor local blood circulation, resulting in metabolites that cannot be cleared and excreted in a timely manner, resulting in corresponding irritating inflammation and frequent cramps; 4. Certain systemic diseases can also lead to the symptoms, such as renal insufficiency, heart failure, etc. Renal insufficiency can easily lead to imbalance in the ratio of calcium to phosphorus, changes in the corresponding internal environment, and muscle dysfunction. Heart failure can lead to water and sodium retention in the body, which can also affect the local blood circulation and cause frequent cramping symptoms.
