The most common causes of low back pain in men are lumbar muscle strain and lumbar disc herniation. Lumbar muscle strain should be avoided by using a hot water bag for localized hot compresses and also anti-inflammatory and pain-relieving medications such as Furtaline cream. The lumbar pain caused by lumbar disc herniation should pay attention to rest, sleep on a hard bed, and can also take pain relief drugs such as Fenbid. Other things that can cause back pain include kidney stones, kidney cysts, and acute pyelonephritis. Kidney stones can be treated with drug lithotripsy, extracorporeal shock wave lithotripsy, and surgery, as well as short-term pain medication such as indomethacin suppositories; kidney cysts need to be treated with puncture and sclerotherapy or surgery; acute pyelonephritis needs to be treated with anti-infection therapy.
