Lumbar protrusion relief after the foot strength recovery time and disc herniation degree, compression time, etc., can not be generalized, such as compression time is short, the disc is slightly protruding, the recovery time is short, generally can be recovered in 1 ~ 2 months, and vice versa is longer. Lumbar herniation refers to the lumbar intervertebral disc herniation, the intervertebral disc fibrous ring rupture, resulting in the nucleus pulposus protrudes, which in turn compresses the nerve root triggered by a series of symptoms, such as lumbar pain, numbness and pain in the lower limbs, lower limb weakness and so on. If the disc herniation is minor, the degree of compression of the peripheral nerves is mild, and can be detected in time for treatment, the strength of the lower limbs can generally be restored in 1~2 months. However, if the disc herniation is severe, or even prolapses into the spinal canal and compresses the spinal cord and nerve roots, and if the symptoms of lower limb weakness persist for a long time without treatment, the time for recovery of hindfoot strength will be relatively longer. In addition, if nerve root necrosis occurs, it may be difficult for the lower limb strength to return to normal. When symptoms such as low back pain occur, it is recommended to go to a regular hospital in time for consultation and active treatment.
