What is a somatic nerve block?
7 min read
Asked by: Jeremy Ballard
Somatic nerves are selectively1 blocked for diagnostic and therapeutic purposes with short acting local anesthetic. This may allow surgeons to confine surgery to the affected levels causing pain. These nerves may on rare occasion also be blocked with neurolytic agents, cryotherapy, or radiofrequency lesioning.
What are the 4 types of nerve blocks?
These four nerve block categories include: therapeutic, diagnostic, prognostic, and pre-emptive. Therapeutic nerve blocks are used to treat chronic pain and various pain conditions. These nerve blocks typically contain local anesthetic which can be used to treat acute pain.
How long is a nerve block supposed to last?
This depends on the type of block performed and the type of numbing medication used. For example, nerve blocks for hand surgery usually last for 6-8 hours, but a nerve block for pain after total knee replacement can last for 12-24 hours.
What does a nerve block actually do?
A nerve block is an anesthetic and/or anti-inflammatory injection targeted toward a certain nerve or group of nerves to treat pain. The purpose of the injection is to “turn off” a pain signal coming from a specific location in the body or to decrease inflammation in that area.
Is a nerve 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.
What is the difference between a cortisone shot and a nerve block?
Steroid injections, or large point injections, are different from nerve blocks only in that they provide a steroid medication in the injection versus an intense numbing agent. The goal of a steroid injection is to provide the joint and body with help to reduce inflammation in order to reduce pain.
What drug is used in a nerve block?
Drugs commonly used for peripheral nerve blocks include lidocaine, ropivacaine, bupivacaine, and mepivacaine. These drugs are often combined with adjuvants (additives) with the end goal of increasing the duration of the analgesia or shortening time of onset.
What are side effects of nerve block?

What happens if nerve blocks don’t work?
Consider a medial branch block
The injections can also give temporary relief if the issue is indeed nerve-related. If a branch block does not work, there is another issue causing back pain. Doctors can try further tests for a proper diagnosis. Speak with a doctor about the possibility of a medial branch block today.
What can I expect after a nerve block injection?
You can expect some post-procedure discomfort or soreness that will also improve within days of the injection. The local anesthetic doesn’t last long and for some people, it may take a while for the steroid to work and provide a long-term benefit. The peak effect of the steroid will usually be between 3 and 10 days.
Is a nerve block considered surgery?
A nerve block, or neural blockade, is a method of producing anesthesia — a loss of feeling used to prevent or control pain. Nerve blocks can be surgical or nonsurgical. Nonsurgical nerve blocks involve injection of a medication around a specific nerve or a bundle of nerves.
Does a nerve block paralyze you?
A nerve block is a local anesthetic injected into or around a nerve or into the spine to temporarily prevent the nerve from relaying pain. A nerve block may cause temporary muscle paralysis or a loss of all feeling in the affected area or in the surrounding area.
When should I take pain meds after a nerve block?
We recommend that you start taking your prescribed pain medication, such as Vicodin®, or Oxycodone®, within 8- 10 hours after your block procedure, before the block wears off.
What does a nerve block feel like when it wears off?
The numbing medicine will begin to wear off about 6 to 24 hours after the nerve block. You will notice a change in the way your limb feels – it may begin to feel less numb, less weak, and you may feel a tingly sensation as if it’s “asleep.” It may take 1-4 hours for the nerve block to completely wear off.
How often can you have a nerve block injection?
Depending on your orthopedic physician’s recommendation, you may receive nerve block injections anywhere between three to six times in a 12-month period. The sooner you start receiving nerve blocks, the better its chance of success, especially when combined with other treatment methods such as physical therapy.
Is Gabapentin a nerve blocker?
Yes, gabapentin is used for treating epilepsy by ‘calming down nerves’. Research has shown that gabapentin by a ‘similar process’ is also effective in helping to relieve certain types of pain.
Do nerve blocks cause weight gain?
Nerve blocks have risks and side effects including: elevated blood sugars, rashes, itching, weight gain, extra energy, soreness at the site of the injection, bleeding and in rare cases, death.
What happens if nerve root injections don’t work?
Mayo Clinic states that in rare instances, untreated severe spinal stenosis may progress and cause permanent numbness, weakness, balance problems, incontinence, and paralysis. That’s why it’s so important to not just treat the symptoms, but address a major root cause of stenosis.
What is a permanent nerve block?
Surgical nerve blocks are permanent. They work by damaging or destroying specific nerve cells. Doctors may use them to treat chronic debilitating pain syndromes.
Is nerve root block injection 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.
Can a nerve block injection make pain worse?
And this is what often happens. Because of the volume of the injection, if that injection does get right next to the nerve, the expansion of the tissue from the volume of the injection can actually cause a localized stress or stretching of the nerve, worsening the inflammation and pain rather than making it better.
Can you drive after having a nerve block?
Please arrange to have someone drive you home after the nerve block, as you will not be able to drive or operate machinery for at least 24 hours after the procedure. You must be healthy on the day of your nerve block.
