Foraminal Injection

A nerve root injection is an injection of a long lasting steroid around a selected nerve root.

The injection is used to reduce the inflammation or swelling around the nerve. This can reduce pain, tingling, numbness or other symptoms you may be experiencing.

Before Your Procedure

  • Certain medications may increase your risk of bleeding and may need to be held prior to your procedure.
  • You may resume these medications the day after your procedure unless otherwise instructed.
  • You may take your pain medication as needed on the procedure day.

During Your Procedure

  • You will lie on your stomach on the X-ray table.
  • Your skin is cleaned and a numbing medication will be given where the needle will be placed, using X-ray guidance to ensure proper placement.
  • Two different medications are injected into the site; a short acting anesthetic agent is injected for temporary pain relief lasting about 4-5 hours and the steroid is injected for longer pain relief, and begins working in 3-5 days.

After Your Procedure

  • You may resume your normal activities as tolerated.
  • Avoid standing up quickly as the medication used can cause dizziness.
  • Notify your doctor of any signs of infection such as fever, redness, swelling or drainage from the injection site.
  • Also notify your doctor of a persistent headache, a rigid or painful neck or sustained dizziness.
  • Your doctor will be contacted with the results of your test and will discuss the results with you.

Dear Friends and Neighbors,

CentraCare care givers have been working around the clock for more than 20 months to care for you, your families and friends during COVID. We are committed to caring for every Minnesotan who needs us, and nothing will prevent us from doing so – even during these never-seen-before times.

The challenge of providing this level of care is that our hospital beds are often full. ERs in all of our hospitals are packed. And our clinical teams are exhausted. Early in the pandemic, our community stepped up in amazing ways to help us. We ask that you again join us in fighting this pandemic together.

How can you help?

  • Please get your COVID vaccines and booster shots. They are proven safe and effective in reducing COVID illness, keeping people out of the hospital, and preventing death.
  • If your situation is not an emergency, please use other care options, including:
  • If this is a medical emergency, call 9-1-1, or visit the ER.

Together, we can do this. Thank you for your support.

Ken Holmen, MD
President and CEO
