Nerve Root Injection

A Nerve Root Injection is a procedure to place a steroid medication (an anti-inflammatory medication) into the area of your back which is causing your pain.

What to expect after this procedure:

  • Temporary relief of pain until the local anesthetic wears off.
  • Some soreness at the injection site for 2-3 days.
  • Slow onset (3-5 days) for the steroid to start working.
  • 10-14 day duration of action for the steroid.

Comfort measures:

  • Use warm, moist heat or ice packs for soreness at the injection sites.
  • Take over-the-counter medications for soreness.
  • Use medication prescribed by your physician.


  • You may resume previous level of activity today as tolerated.


  • You may resume your normal diet.
  • The steroid may cause temporary weight gain, swelling of the hands or feet, irregular menstrual cycle, hot flashes, or facial flushing. These symptoms will subside as the steroid tapers off.
  • If you are diabetic, you may see a temporary rise in your blood sugar. Notify your physician if the levels are above the limit set by your physician.

Notify your physician if you experience:

  • Sign of infection such as fever above 100 degrees, chills, redness, swelling or drainage at the site of the injection.
  • New numbness or weakness in your legs.
  • If you do not already have a follow-up appointment and your pain is not improved after 7-10 days, call to schedule a return appointment with your physician at the Pain Center.
