into the lumbar epidural space. Group B common complaint of young adults in case was given injection methylprednisolone of intervertebral disc herniation. Its sodium succinate 80 mg with 2 ml of 0.5% incidence is high in India due to difficult bupivacaine diluted in 8 ml of normal saline working as well as living environment. Objectives: The present study was carried
Observations: The success rate in group A
out to compare the efficacy of injecting was found to be 68% and the success rate in group B was found to be 80%. The visual methylprednisolone sodium succinate in analog scale score in group A was the management of chronic low back pain. decreased by 20% after one week and by 50 Patients and Methods: This study was
