How effective is injection therapy for treating lumbar disc herniation?

Injection therapy for lumbar disc herniation provides direct and effective symptom relief, but should be used as part of a comprehensive treatment plan based on individual patient conditions and physician recommendations. Injections of medications such as mannitol can help reduce nerve edema and swelling of soft tissues surrounding the herniated disc, thereby alleviating pain caused by nerve irritation. Sacral canal infusion delivers local anesthetics, steroids, and other medications into the epidural space, producing anti-inflammatory effects and promoting nerve tissue repair. When combined with other treatment modalities such as pharmacological therapy and physical therapy, injection therapy can accelerate the recovery process of lumbar disc herniation. As one of multiple available treatment options, injection therapy should be selected according to individual patient circumstances and under medical guidance. Therapeutic outcomes may vary due to individual differences, and treatment should be regularly evaluated and adjusted according to patient response and disease progression.
