Straightening of the physiological curvature of the lumbar spine may cause numbness in the legs, and in severe cases, it may also involve the cauda equina nerve, causing cauda equina syndrome.
Under normal circumstances, when the physiological curvature of the lumbar spine is straightened, the structure of the lumbar spine will be changed, which may affect the nerves, muscles and ligaments near the lumbar spine. When the nerves passing through the lumbar spine are compressed, it is easy to cause numbness of the legs, which may be accompanied by lumbar pain and radiating pain in the lower limbs.
If the lesion continues to aggravate and is not treated in time, it may involve the cauda equina. When the cauda equina is severely damaged, incomplete paralysis of the lower limbs and dysfunction of urinary and fecal functions may occur, which will seriously reduce the quality of life.
Therefore, after the symptoms of lumbar spine physiological curvature straightening appear, it is recommended to consult a doctor as soon as possible for examination and treatment to avoid continuous aggravation of the lesion.
