Nerve Root Block for Pain Relief

Back pain or lower back pain is a familiar issue for many people, both young and old. Low physical activity and sedentary work can exacerbate back pain, especially in younger people due to poor posture at desks or computers, and in middle-aged and older adults due to degenerative conditions.

Sometimes, back pain can result from the compression of nerve roots in the spinal canal or its opening. This condition can have various causes, such as a spinal hernia, and may also be influenced by conditions that affect the musculoskeletal system, like rheumatoid arthritis or lumbar osteoarthritis. In rare cases, compression can result from epidural abscesses, tumors, or meningiomas.

In some cases, medications alone are sufficient for treating nerve root compression, but often, nerve root block injections are more effective.

 

What is a Nerve Root Block?

 

A nerve root block is an injection of a mixture of anesthetics and anti-inflammatory drugs administered to the nerve root under the guidance of a mobile X-ray machine (C-arm).

This procedure is prescribed and performed by a pain specialist who is experienced in interventional pain management.

 

How is the Nerve Root Block Procedure Conducted?

 

The nerve root block is performed in a sterile environment with a C-arm for precision. Medication is administered through a needle by a specialist. After the needle is removed, the area is cleaned, dried, and covered with a sterile bandage, which can be removed after 12-24 hours.

Following the procedure, 1-2 hours of rest is recommended. Driving is discouraged, so it’s advised to come with someone who can assist you. The injection site should not be exposed to heat sources (like hot baths or saunas) for at least one day.

 

Is the Nerve Root Block Painful?

 

Patient experiences vary, but the injection may cause sensations of burning or pain at the injection site. These are usually mitigated by local anesthetics or sedation if requested by the patient.

Injected medications usually start working within 1–3 days. In the first few days after the injection, the pain may intensify, and mild soreness may be felt at the injection site. It is recommended to apply a cold compress to the injection site 3–4 times a day. After the procedure, you will discuss the further course of treatment with your pain specialist. This plan is individualized for each patient.

  

Aftercare Following a Nerve Root Block

 

One of the most common psychosomatic disorders manifests as pain; therefore, it is often not advised to treat pain solely with medication. The patient can do the most to help themselves. Movement and physical activity, within your capabilities, are essential. Try to view your surroundings with joy and simplicity, and identify even the smallest things that bring you happiness. Avoid setting unrealistic or unachievable goals and don’t dwell on the fact that you cannot accomplish them quickly. Learn to relax and manage stress, anxiety, and low moods. Negative thoughts significantly impact pain. Sometimes, this will be a long process requiring considerable willpower, but don’t give up—small steps toward better well-being always pay off in the long run.

Remember that when doing any physical work, you should regularly change your body position. When carrying heavy objects, stand upright and hold them with both hands as close to your torso as possible—do not rest them against your side, but rather lift them onto your shoulder if needed. When lifting objects from the ground, squat first and then lift, and when setting them down, squat again before lowering them. If you have a sedentary job, you can always perform a few simple exercises to reduce fatigue, relieve back pain, and improve productivity.

Equally important is an individualized exercise program tailored to you by a physiotherapist (incorrect exercise can do more harm than good), massage (note that improper massage for chronic back pain can worsen the condition), proper posture, sitting, and movement techniques, as well as wearing comfortable footwear with a sturdy, well-formed sole. Additionally, don’t forget the importance of getting a good night’s sleep.
