Numbness in the lumbar region is most commonly caused by a herniated lumbar disc, which then compresses the nerves and induces numbness in the lumbar region or soreness and pain in the lumbar region, as well as pain in the lower extremities, radiating pain, or abnormal sensation and other symptoms. If the condition is determined to be caused by a herniated lumbar disc, conservative treatment measures can be given to patients with mild cases. First of all, strict bed rest should be given, then do not bend over to bear weight, and with local traction, massage, acupuncture and other measures to assist in treatment. You can also apply nerve-nourishing and anti-inflammatory and analgesic drugs, such as lumbar pain capsules, methylcobalamin tablets, vitamin B12, etc. If conservative treatment measures are ineffective, you can also consider giving surgical measures for treatment.
