If the nerve roots are significantly compressed, there will be decreased sensation in the dorsum of the anterior lateral calf and decreased muscle strength in the extension of the second toe. The exact degree of lumbar disc bulge can be accurately determined by magnetic resonance imaging of the lumbar spine. The majority of patients can try conservative treatment, such as traction, and bed rest and recuperation. When the pain is severe, you can use painkillers, such as lo-fen-zine extended-release tablets, and drugs that activate blood circulation and resolve blood stasis, such as blood circulation and pain capsules, as well as the nerve-nourishing drug methylcobalamin, most of which can be significantly relieved by conservative treatment. Avoid prolonged standing, prolonged sitting, repeated bending and heavy physical labor, which can help the recovery of lumbar disc 4/5 bulge.
