What is wrong with back pain that cannot be bent but only straightened?

The inability to bend over in low back pain may be due to lumbar disc herniation, lumbar spondylolisthesis, lumbar degeneration, and isthmic fracture. In addition, infectious diseases of the lumbar region, such as lumbar spine tuberculosis or intervertebral infection, and tumors of the lumbar spine, may also present with lumbar pain. Observe whether there are other combined symptoms, such as lumbar spine tuberculosis may be combined with hot flashes and night sweats. Lumbar disc herniation may be accompanied by radiating pain in the lower limbs. Go to the orthopedic department in time to see a doctor for an interview. The doctor will make a preliminary judgment with the physical examination and improve the lumbar spine X-ray examination to understand whether there is obvious lumbar spine slippage and bone abnormality. If necessary, further magnetic resonance examination to determine whether there is a lumbar spine tumor or other diseases. In case of obvious pain, temporarily give painkillers to relieve pain and choose the appropriate treatment according to the examination of different causes.
