For patients with leg numbness caused by lumbar sprain, the main cause is the protrusion of the disc after the lumbar sprain, so that the protruding disc will compress the nerve roots in the lumbar area, resulting in leg numbness. Therefore, the possibility of self-healing is relatively small, after the numbness appears more bed rest, avoid excessive weight-bearing activities of the waist. A CT examination of the lumbar region can be performed to see the size of the herniated lumbar disc and the degree of pressure on the nerve roots. If the disc herniation is relatively small and there is no obvious nerve root compression or edema, blood-stasis activating and neurotrophic drugs can be used, and lumbar traction and physiotherapy treatment can be performed if necessary. If the herniated disc causes significant nerve root compression and edema, surgery is required to remove the herniated disc to relieve the nerve root compression and relieve the patient’s leg numbness.
