Most of the numbness and radiating pain in the lower extremities are generally due to the compression of the nerve by the herniated disc. In addition, degenerative hyperplasia of the lumbar spine is not excluded, as the formation of bone spurs leads to narrowing of the lateral saphenous fossa, which causes numbness and radiating pain in the lower extremities, and most of these two causes are due to nerve root irritation, resulting in numbness. For numbness in the lower extremities caused by lumbar protrusion, CT or MRI of the lumbar discs should be performed to determine the degree of compression. If the lumbar disc is prolapsed, surgery should be considered at this time. If the nerve compression is not very serious at the stage of bulge and protrusion, conservative treatment can be considered, which can include traction and some drugs to relieve nerve root edema, such as mannitol. In addition, oral medications such as Diosmin can also be considered for improvement. At the same time, nerve nutrition therapy is needed, and most of the nerve nutrition options are methylcobalamin and vitamin B1.
