Nerve root block injections are a highly effective treatment for nerve-related pain that travels into your arm or leg. This type of pain is often described as sciatica when it affects your leg, or as shooting or burning pain when it affects your arm. A nerve root block targets the specific irritated nerve root that is causing your symptoms, helping to reduce inflammation and calm the pain signals.
At Ramsay Health Care, nerve root block injections are carried out by experienced consultants using X-ray guidance for accuracy. Patients benefit from fast access to appointments, clear explanations at every stage and transparent self-pay pricing.
Whether you are exploring treatment for the first time or have been living with nerve pain for some time, this page explains what nerve root blocks are, how they work and what to expect.
A nerve root block injection places a small amount of local anaesthetic and steroid around your spinal nerve root. Your nerve root is the point where a nerve leaves your spine and travels into your arm or leg. When this nerve becomes irritated or compressed, it can cause pain that radiates along its pathway.
This type of pain is known as radicular pain. Radicular pain in the leg is often called sciatica. Radicular pain in your arm may feel like shooting pain, tingling or numbness caused by a trapped nerve in your neck.
A nerve root block has two purposes. It can relieve pain by reducing inflammation around your nerve. It can also help diagnose which nerve is responsible for your symptoms. If the injection reduces your pain, it confirms that the targeted nerve root is the source.
A nerve root block is a day-case procedure. You arrive at the hospital, have the injection and go home the same day.
The procedure is guided by X-ray or CT imaging to ensure your injection is placed precisely around the correct nerve root. Before your injection, a local anaesthetic is used to numb your skin. Once the area is numb, your consultant places a fine needle near your nerve root and injects a combination of local anaesthetic and steroid.
The anaesthetic provides short-term relief. The steroid reduces inflammation and can provide longer-lasting improvement.
You will need someone to drive you home, as you cannot drive yourself after the procedure.

Most people return to normal daily activities within twenty-four to forty-eight hours. Some soreness at the injection site is normal and usually settles quickly.
It is also common for pain to temporarily worsen for a day or two before improving. This happens because the steroid takes time to work. A short flare-up is expected and not a sign of a problem.
If you have temporary numbness or weakness in your arm or leg after the injection, this usually settles within a few hours.
Nerve root block injections are generally safe. Your consultant will explain all relevant risks before you consent to treatment.
Common side effects include:
Soreness or bruising at the injection site
Temporary numbness or weakness in your arm or leg
A short increase in pain before improvement
Less common side effects include:
Infection
A temporary drop in blood pressure
Headache caused by a dural puncture
Serious complications are very rare.
If the injection does not provide lasting relief, this does not mean the procedure has failed. It simply means the nerve may need a different type of treatment. You can read more about next steps below.
If a nerve root block provides only short-term relief or does not improve symptoms, your consultant will discuss other options. These may include:
Radiofrequency ablation uses heat to disrupt pain signals from your affected nerve. This can provide longer-lasting relief.
If imaging shows a structural cause such as a disc prolapse, your consultant may discuss referral to spinal surgery. Explore lumbar discectomy
Your consultant will always start with the least invasive option and only escalate treatment when clinically appropriate.

A nerve root block is an injection of local anaesthetic and steroid around a spinal nerve root. It is used to relieve nerve-related pain and to help diagnose which nerve is causing your symptoms.
Nerve root block relief can last from several days to several months. Some people experience long-term improvement, while others may need repeat treatment or a different intervention.
Ramsay offers fixed, transparent pricing that is agreed before treatment. Price is dependent on your local hospital
Most people return to normal activities within twenty-four to forty-eight hours. Temporary soreness or a short flare-up of pain is common and usually settles quickly.
The area is numbed with local anaesthetic first, so most people feel only mild pressure during the injection. Some soreness afterwards is normal.
