Common Nerve Block Procedures for Pain

A nerve block is an injection to lower the intensity of inflammation in an effort to switch off the pain signal frequency. Medical science has developed more rapidly over the past few years. You may be suffering from some pain, and you may opt for new medical procedures for pain relief – nerve block is one of these. 

Though it's in use now for quite some time, it has its benefits and gives an easy time-adjustment factor to schedule your surgery, long-term medication, etc., to address varying pain levels.

Typically, nerve block injections may help to reduce pain temporarily. You may consider certain points prior to opting for a nerve block procedure to make it easy.

An Insight into Nerve Block Procedures

Permanent pain can make your life miserable, keeping you from even doing simple tasks and chores. For people suffering from acute or very high-level of pain, the nerve blocking process has become a beacon of hope during the treatment phase.

Injections for local anesthetic and/ or steroids to affected nerves can help get quick relief from pain and may improve quality of life. The ultimate goal is to help patients who intend to avoid surgery and any active participation in physical therapies.

A pain-specific-area-injection may be another option to relieve pain. These injections can help pinpoint the area or nerve location that may be the origin of pain.

Your physician or healthcare clinic will best advise you on how and when to go for a nerve block. However, you may look into other aspects.

Fear part - The Injection

Many people avoid injections due to the fear of needles. However, they become inevitable when dealing with certain types of pain. Patients with arthritis may sometimes have to get seven or maybe eight needles injected into different body parts. 

The impact of local anesthesia injection minimizes the needle pain, or IV sedation can help decrease repetitive insertion of injection anxiety. Fearing injection will not resolve the pain level. Face it.

In the same context, a low-powered set of x-rays allows the doctor to see the bone structures during the process of the nerve block. Indeed, it helps the right placement of the needle to reduce any later stage complications. 

Multi-type response to a nerve block

Many people assume nerve block is an instant pain relieving method. For others, it may be a barrage of injections, eventually easing out the pain. In the medical world, pain is quite a personal phenomenon, and it varies from the lowest to the highest pain thresholds.

If you have had chronic pain for more than a decade, it may evolve into multiple pain points or conditions. Let’s say the first injection in your spine may be diagnostic; based on its response, you may need a different or new method to relieve the pain. It's a way to accurately find the source of pain to avoid any therapy or surgery.

Post-procedure Soreness

This is common to have soreness, swelling, or pain within days after nerve blocking. This is a usual occurrence, and you cannot avoid it, as local anesthesia will subside in considerable time. Sometimes, the steroid may take a long time to work effectively, resulting in long-term advantages.

A steroid’s top effect will come somewhere between 4 and 10 days times. In certain cases, before steroids show any soothing effect, the patient is already getting prepared for another injection. The patient’s response to the first injection will decide the future course of action the healthcare center or physician will take. This is purely in order to find the exact location of the nerve or the point causing pain.

Treatment relevancy with your Medical History

You may need injections periodically, depending upon your previous medical history, physician’s diagnosis, and your condition. 

The ultimate goal is to lower the pain and increase your probabilities to partake in physical therapy. This may be instrumental in avoiding surgery for some patients.

Common Nerve Block Types

There are two common types of nerve-blocking procedures, including different methods.

Non-Surgical Nerve Block

This is a temporary nerve block procedure. Doctors or physicians use these methods for short-term relief of pain or like anesthesia during an operation. 

Epidural Nerve Blocking Process

It involves injecting an analgesic or some steroids around the nerve outside your spinal cord. Mostly it's used during child-delivery.

Spinal Anesthesia or Analgesia Nerve Blocking

It’s also a nerve-blocking process, where only the doctor will execute injection into the fluids that surround your spinal cord.

Sympathetic Nerve Blockade

The doctor will administer a drug to prevent the pain emanating from the nervous system by numbing the nerve. It is a temporary or makeshift arrangement to reduce pain.

Surgical Nerve Blocks

These are permanent nerve blocking procedures. It involves completely destroying the specific nerve cells causing pain. 

Sympathetic nerve block

In this case, doctors use drugs to permanently block the pain from the origin by destroying the nerve.

Neurectomy nerve block

It involves a process where a part or complete removal of peripheral nerve gets blocked, stopping the pain signals.

Rhizotomy nerve blocking

In this method, the doctor completely destroys the affected nerve from the spine.

Trigeminal Nerve Block Technique

This technique provides a long pain relief span – few months at most, by destroying nerve fibers and Wallerian degeneration of axonal fibers and cells. Nonetheless, neurons will re-generate in about a 4-5 months period. However, it may take 10 to 14 days to achieve complete relief from the pain. 

Supra Orbital Nerve Block (Forehead)

This method is effective in providing immediate localized anesthesia for multiple injures like complex lacerations to the face, forehead, burns or abrasion to the forehead, pain relief from acute herpes, and removal of foreign bodies. 

This method allows for minimum anesthetic use to get intended anesthesia over a large area in comparison to local ingress of anesthesia.

Maxillary Nerve Block (Upper Jaw)

A maxillary nerve blocking procedure involves administering an injection into the nerves near the upper bone plate of the jaw to numb the face part. It provides regional anesthesia to the nose, upper jaw, mouth, and cheeks.

More Nerve Block Types

Single Injection Nerve Block

It’s a self-explanatory nerve block method. A single injection of numbing medication will numb the area around the painful nerve. Its longevity depends on the type of medicine, the intended area of the block, and your response to it. It’s helpful in relieving post-surgery pains, and it will typically work for 3 to 18 hours at max. It may not subside the pain; if pain persists, you can get additional pain medication. 

Continuous Nerve Block

This process involves placing a catheter next to the nerves in question. The catheter at the back end is connected to a pump to keep the affected area numb for 60-70 hours.

Lower Extremity Nerve Block 

Lower extremity nerve block relieves the pain in your pelvis area, thighs, ankle, feet, and knees. A normal surgery for the lower extremity at times may need two blocks at max; else, one will do. You may find your leg numb for a considerable amount of time post-surgery.

Upper Extremity Nerve Block 

Surgery on the chest or abdomen may need one or more injections. It numbs a specific or limited area. Upper extremity nerve block covers pain in your hand, wrist, arm, and shoulder. The doctor may administer the injection closer to your spine or the abdomen area.

Sometimes the block is closer to the spinal area and requires epidural or spinal anesthesia. It may get done in a single injection, or the doctor may use a catheter to control pain. 

Nerve Blocks may be Neurolytic or Non-Neurolytic. 

Neurolytic Blocks

This involves administering a neuro-destructive agent like phenol or alcohol. It’s in close proximity of the target nerve to get or produce analgesic effects. These blocks are not common for extreme pain.

Non-neurolytic Blocks

It is the application of local anesthesia that gives a transient blockage. Besides its effectiveness for sympathetically maintained pain, it may well be in use as a diagnostic procedure to locate the source of pain.

In some patients, it may have varying degrees of impact without lowering its importance in helping reduce pain.

Conclusion

Nerve blocking is part of medication for relieving all types of pains near or onto the nerves.

The nerve block medication may include steroids, opioids, and anesthetic or steroids. In case of urgency for severe pain, destroying a nerve may become the primary or only way of curing the pain.

Nerve blocks may not be a good idea for many people; nonetheless, this can lead you to some peace of mind, helping you to live without pain. 

A nerve block is a process that pain management doctors and physicians use to numb a particular nerve to treat certain types of pains. Never blocking may not be a lasting treatment for all pains, as in certain cases, nerve blocking may be dangerous or not possible.
