Epidural injections are typically administered in a hospital or outpatient clinic. They are used to deliver pain relief or anesthesia and are considered safe and effective. The procedure involves injecting medication into the epidural space, which is located near the spinal cord. This can be done in several ways, including using a needle or a catheter. While the injections are generally not painful, patients may experience some pressure during the procedure.

Epidural injections are performed in hospitals or outpatient clinics
Epidural injections are generally performed in hospitals or outpatient clinics. An epidural is an injection near the spinal cord, and there are two types: one for pain management and the other for administering anaesthesia.
The procedure for an epidural injection is as follows: the patient changes into a gown and lies face down on an x-ray table. If this position is painful, they may sit up or lie on their side in a curled position. The healthcare provider then cleans the area of the patient's back where the needle will be inserted and may use medicine to numb the area. The patient may also be given medicine to help them relax. The provider then inserts a needle into the patient's back, using an x-ray machine to guide the needle to the correct spot.
There are several different ways to perform epidural injections, including the interlaminar and transforaminal techniques. The interlaminar technique involves inserting a needle between two laminae in the spine to reach the epidural space. The transforaminal technique involves inserting the needle through the foramina, which are openings through which nerve roots exit the spine.
Epidural injections are typically used to manage chronic pain and inflammation. They can be used to treat conditions such as herniated discs, spinal stenosis, radiculopathy, degenerative disc disease, and sciatica. Epidural injections can also be used to provide anaesthesia during labour or before surgery.
While epidural injections are generally safe, there are some potential side effects and complications. These may include dizziness, headache, nausea, nerve root damage, infection, and allergic reaction to the medication. It is important for patients to remain still during the procedure and to inform their healthcare provider if they experience any complications after the injection.

They are used to relieve pain or deliver anaesthesia
Epidural injections are used to relieve pain or deliver anaesthesia. They are injected near the spinal cord, in the epidural space, which surrounds the spinal cord like a sleeve. This space contains fat, spinal nerves, blood vessels, and connective tissue.
There are two types of epidural injections: those that deliver anaesthesia and those that are steroid injections for pain relief. Both are considered safe and effective, and your healthcare provider will determine which type you need. Anaesthesia epidurals are typically used during labour or before surgery. Steroid epidurals, on the other hand, are used to manage chronic pain caused by irritation and inflammation of the spinal nerve roots, often in the lumbar region of the spine. This type of chronic pain is called lumbar radiculopathy, or radicular pain, and can radiate from the low back to the hips, legs, and feet. Steroid epidurals can provide temporary pain relief for three months or more, helping individuals resume daily activities and potentially avoiding the need for surgery.
The procedure for epidural steroid injections involves the patient lying face down on an X-ray table, or sitting up or lying on their side if that position is painful. The area of the back where the needle will be inserted is cleaned and may be numbed. The patient may also be given medicine to help them relax. The provider then inserts a needle into the back, guided by an X-ray machine to ensure it reaches the correct spot. A steroid or corticosteroid is injected, sometimes mixed with a local anaesthetic. This medication decreases swelling and pressure on the nerves, providing pain relief.
While epidural steroid injections are generally safe, there are some potential side effects and complications, although these are rare. They include dizziness, headache, nausea, nerve root damage, infection, allergic reaction, and bleeding around the spinal column. It is important to be still during the procedure and not to have the injections too often, as this can weaken the bones of the spine or nearby muscles.

There are two types of epidural injections: anaesthesia or steroids
Epidural injections are typically administered in a hospital or outpatient clinic. They are injections near the spinal cord, and there are two main types: anaesthesia or steroids. Both are considered safe and effective, and a healthcare provider will determine which type of epidural injection is required.
Anaesthesia
Anaesthesia blocks feeling and pain. Anaesthetic medication is injected into the epidural space, which is the area around the spinal nerves. This stops pain signals from travelling from the spinal nerves to the brain. The nerves are temporarily turned off, and the effect lasts for a duration dependent on the dosage.
Steroids
Epidural steroid injections (ESI) are used to manage chronic pain and inflammation. A steroid, typically a corticosteroid, is injected into the epidural space. ESIs last longer than anaesthetic epidurals, providing pain relief for weeks or months. They work by coating the irritated nerves, reducing swelling and pressure.
Types of Steroid Injections
There are several types of steroid injections, including:
- Transforaminal: The needle is inserted through the foramina, which are the openings where nerve roots exit the spine. This is a highly targeted approach, providing immediate pain relief.
- Interlaminar: The needle is inserted between the laminae, which are the protective layers of bone in the spine. This is a more general route, providing a wider medication distribution.
- Caudal: This type of injection targets the lower spine and can help with back problems such as herniated discs and leg pain.
Side Effects and Complications
Side effects and complications from epidural injections are rare but can include dizziness, headaches, nausea, nerve root damage, infection, and allergic reactions. It is important to remain still during the procedure, and patients are monitored for 15 to 20 minutes afterwards.

The procedure involves inserting a needle into the epidural space
Epidural injections are usually administered in a hospital or outpatient clinic. The procedure involves inserting a needle into the epidural space, which is the area outside the sac of fluid around the spinal cord. This space is where spinal nerves are located.
Before the procedure, the patient will change into a gown and lie face down on an X-ray table. If this position causes pain, the patient may sit up or lie on their side in a curled position. The healthcare provider will then clean the area of the back where the needle will be inserted and may use medicine to numb the area. The patient may also be given medicine to help them relax.
Once the patient is prepared, the provider will insert a needle into the patient's back. An X-ray machine or other imaging machine may be used to guide the needle to the correct spot in the lower back. The needle is inserted between two laminae in the spine, or through the foramina, which are openings through which nerve roots exit the spine.
After the needle is in the epidural space, the provider may inject a contrast material to ensure that the medication reaches the targeted nerves. The provider will then slowly inject the medication, which is typically an anti-inflammatory medication such as a steroid or corticosteroid. In some cases, a mixture of a corticosteroid, normal saline, and a local anesthetic may be used.
Once the injection is complete, the provider will apply pressure to the injection site to prevent bleeding, clean the area, and apply a dressing. The patient will then move to a chair or bed to rest for a few minutes to an hour to ensure they don't have any reactions to the medication.

Potential side effects and complications are rare but can occur
Epidural injections are generally considered safe and are often carried out in hospitals or outpatient clinics. They are used to manage pain or deliver anesthesia. While side effects and complications are rare, they can occur.
The most common side effect is a headache, which is usually not serious. This can be caused by spinal fluid leakage, also known as a dural puncture, where the needle inadvertently enters the spinal cord's outer membrane. This can lead to a decrease in cerebrospinal fluid pressure in the brain, resulting in a headache. Other potential side effects include dizziness, nausea, and increased pain in the leg due to nerve root damage.
In some rare cases, more serious complications may occur. For example, an infection at the injection site or elsewhere in the body, such as meningitis or an abscess, can develop. There is also a risk of an allergic reaction to the medication, which can cause hot flashes or a rash. Nerve damage is another potential complication, which may lead to numbness or weakness in the legs, or even permanent neurological deficits.
It is important to note that receiving epidural injections too frequently or at too high a dose can weaken the bones of the spine or nearby muscles. This is why providers typically limit patients to two or three injections per year.
