The treatment of lumbar disc herniation leading to lumbar spinal stenosis and compression of nerves leading to leg pain includes non-surgical and surgical treatment. Non-surgical treatment includes bed rest for 3-5 weeks to relieve pain in the back and legs, appropriate physical therapy to eliminate local muscle spasm and fatigue, and non-steroidal painkillers such as lexon, indomethacin, ibuprofen, etc., as well as blood-stasis-activating drugs to reduce pain. In severe cases, corticosteroids can be injected into the nerve roots to reduce the edema of the nerve roots to improve the symptoms. A stiffer lumbar brace can be applied to prevent lumbar hyperextension and to exercise the low back muscles. If the effect is not obvious after three months of non-surgical treatment and the symptoms are severe, surgical treatment can be performed. Indications for surgical treatment include extensive compression of the nerve roots and cauda equina nerve, paralysis, and urinary disorders.
