How long do root nerve block injections last?

​

The imaging itself is painless. The effects of the injection are usually immediate. It only takes a short time for the medication to achieve pain relief. However, nerve blocks are only a temporary fix—they typically last for up to one or two weeks and then wear off as they are absorbed by your body.

​

Is a nerve root block painful?

​

After the skin is numb, the procedure needle feels like a bit of pressure at the injection site. If you experience any pain during the procedure, your doctor will inject more local anesthetic as needed. The actual placement of the needle is not painful. However, keep in mind the nerve root is pinched and irritated.

​

Is a nerve root block the same as an epidural?

​

A selective nerve block targets a specific nerve that needs to be managed by injecting the medication around this structure whereas an epidural injection is injected into the epidural space of the spinal cord to offer symptomatic relief to a larger area of pathology.

​

How does a nerve root block work?

​

A nerve root block is an injection of local anesthetic (numbing medicine) and steroid injected under X-ray guidance into the area where the nerve exits the spinal column. A nerve root block is usually ordered by your doctor for pain in the arm or leg that follows the path of a single nerve.

​

What happens when a nerve block wears off?

​

As the nerve block wears off over ten to twenty hours, muscle function will return followed by sensation. While the limb is numb, care must be taken to avoid unintentional injury such as crushing, cutting or burning the anesthetized arm or leg.
