Spinal nerve block FAQs

Learn more about getting a spinal nerve block injection in these frequently asked questions.

Spinal nerve blocks are often used to treat the following back and spine conditions:

  • Sciatica
  • Spinal arthritis
  • Lower back pain
  • Chronic headaches and migraines
  • Cancer-related pain
  • Complex regional pain syndrome
  • Other types of nerve pain

A nerve block can make your arms and legs feel weak, which may limit your ability to walk temporarily. This will only last for a short time, and your team will support you to get back on your feet as quickly as possible after your injection.

You shouldn’t drive for 24 hours after a nerve block injection. If you feel well after this time, you can start to drive again.

When you have a spinal nerve root block injection, you might experience:

  • Weakness or discomfort in your arms and/or legs.
  • Headaches.
  • Slightly heightened discomfort in the days after your procedure.
  • Heightened blood sugar levels for a few days (this is important to note if you have diabetes).

Other risks include temporary or permanent nerve damage, longer-lasting limb numbness or weakness, and bleeding into the epidural space of the spine. These risks are much less common than the side effects above, but consider them when weighing up your back pain treatment options.

The anaesthetic will last for just a few hours. The anti-inflammatory effects of the steroid, however, should last much longer, often providing several weeks to several months of pain relief.

Nerve block injections may be a little uncomfortable, but most patients agree that the medium-term pain relief they feel is worth it.

You’ll feel a small sting as the local anaesthetic is injected and possibly some slight discomfort as the nerve is treated. When the anaesthetic wears off you might feel more pain, but this can usually be managed with over-the-counter painkillers.

Nerve block injections are reported to have success rates of up to 80% for patients with a slipped disc in their lower back. This may vary depending on your condition and the extent of your pain.

You’ll probably need to take a couple of days off work for the procedure and immediate recovery, but many patients can start working again after 48 hours. This depends on your level of discomfort and the nature of your job.

The spinal nerve block procedure lasts around 15 to 20 minutes. But you can expect to be at the hospital for initial assessment and post-procedure monitoring for a few hours.

A spinal nerve block consists of a local anaesthetic (which works immediately) and a steroid (which works within two to five days). You might feel discomfort between the spinal nerve block wearing off and the steroid medication kicking in.
