Acute back pain can be seen in acute lumbar sprain, lumbar disc herniation, kidney stones, etc. There is no fastest way to relieve the pain, including medication and physical therapy. Acute lumbar sprains can be relieved with non-steroidal anti-inflammatory drugs, such as ibuprofen and acetaminophen, as well as cold and hot compresses. Bed rest is necessary to avoid re-injury. Commonly used medications for lumbar disc herniation include NSAIDs (e.g., ibuprofen) and muscle relaxants (e.g., chlorzoxazone). In normal times, you should maintain good sitting and standing posture and avoid overwork. If it is caused by kidney stones, painkillers, such as ibuprofen, pethidine, etc., can be applied, and at the same time, lithotripsy treatment should be carried out, and the commonly used methods include extracorporeal shock wave lithotripsy. However, it should be noted that the medication must be used under the guidance of the doctor, do not self-medication.
