Nerve Root Block Injections:
Dual Roles in Diagnosis and Treatment

Epidural injections are efficient same-day procedures, commonly performed under local anesthesia. They utilize fluoroscopy (a type of portable X-ray) or, in challenging cases, a CT scan. This procedure serves both a diagnostic and therapeutic purpose, offering relief to patients.

1. The Procedure in Brief

  • Same-Day: Epidural injections are completed in a single day.
  • Guidance: Fluoroscopy or CT scans ensure precision.
  • Admission: You’ll be admitted on the procedure day for initial checks.
  • Anesthesia: Local anesthesia is used, sometimes with sedatives.

2. Needle Placement and Medication

  • Needle Guided by X-Ray: A needle is precisely guided using X-ray towards the nerve root.
  • Position Confirmation: Dye visible on X-ray confirms needle placement.
  • Medication: A combination of local anesthetic and steroids is administered around the nerve root.
  • Patient Experience: Some patients may feel a gush sensation traveling down the leg during the procedure.

3. Post-Procedure Care

  • Recovery and Monitoring: Afterward, you’ll be transferred to a recovery area and monitored.
  • Temporary Effects: Temporary numbness or weakness may occur.
  • Accompaniment: Have someone available to drive you home.
  • Symptom Changes: Rarely, symptoms may temporarily worsen; continue regular painkiller medication.

4. Diagnostic Role:

Pain Diary: If it’s a diagnostic procedure, maintain a pain diary to discuss your symptoms during follow-up clinic visits.
