Primary outcome was radicular leg pain evaluated by LegVAS. A diagram was presented to the patient with a score of 0 denoting “no pain”, and a score of 100 denoting “pain as bad as it could be.” BackVAS, ODI adverse event, and failure of treatment were also addressed at baseline, 2, 6, 12, 24 weeks. Patients were observed for acute postoperative complications for at least 4 to 6 h. Medication prescribed was paracetamol and tolperisone. All patients used ice pack for 1 day and lumbar support for 3 days after the injection. Patients were advised of acute complications such as soreness, itching, neurological deficits, and infection. Limited back activities were recommended for 1 week. There was no drop out, and no cross-over group. Treatment failure was defined as persistent or deteriorated pain. MRI was requested when there was persistent pain or new onset of pain.
