Steroid injectionsFacts on Epidural Steroid Injection. An epidural steroid injection is performed to help reduce the inflammation and pain associated with nerve root compression. Nerve roots can be compressed by a herniated discspinal stenosis steroiids, and bone spurs. When the nerve is compressed it becomes inflamed.

Epidural Steroid Injection Side Effects & Recovery
Facts on Epidural Steroid Injection. An epidural steroid injection is performed to help reduce the inflammation and pain associated with nerve root compression. Nerve roots can be compressed by a herniated disc , spinal stenosis , and bone spurs. When the nerve is compressed it becomes inflamed. This can lead to pain , numbness, tingling or weakness along the course of the nerve. This is called radiculopathy. The goal of the epidural steroid injection is to help lessen the inflammation of the nerve root.
The epidural space is located above the outer layer surrounding the spinal cord and nerve roots. An epidural steroid injection goes into the epidural space, directly over the compressed nerve root. Types of Epidural Steroid Injections. There are several types of epidural steroid injections. They can be described according to the location they are given. Injections in the neck are called cervical epidural injections, while injections in the middle back are thoracic epidural injections, and injections in the low back are called lumbar epidural injections.
They can also be described according to the path of the needle. Most epidural steroid injections are placed between the lamina, known as interlaminar epidural steroid injections.
The lamina are portions of the bones on the back side of the spine that are arranged like shingles. The needle is aimed upwards toward the head and passes between two adjacent lamina. Another type of injection is a transforaminal steroid injection. In this case the needle passes along the course of the nerve and enters the spine from a more diagonal direction.
Epidural Steroid Injection Preparation. The patient will be given specific instruction from the doctor prior to coming for the injection. In most cases the patient can eat a small meal several hours prior to the injection. The patient can continue their normal medications with the exception of any blood thinners or anti-inflammatory medications. Please be sure to discuss all medications the patient is taking with the doctor when scheduling the injection to discuss the possibility of discontinuing any of them prior to the injection.
After the patient arrives for your epidural steroid injection an intravenous IV line will be placed in one of the veins. The patient may be given a medication to help them relax during the procedure. The patient will then be placed on an X-ray machine over a bolster to help open up the spaces between the bones in the back. An X-ray will be obtained to verify the proper level for the injection. The skin will be cleaned and prepared for the injection.
The skin will then be injected with a medication to numb the area. Epidural Steroid Injection Procedure. After the area is prepared and numb the doctor will insert the needle though the skin toward the spine.
Once the needle is in the proper space a small amount of dye may be injected to verify the position of the needle on the X-ray. After this the mixture of numbing medication and steroid is injected in the epidural space. The needle is then removed and a band-aid is placed over the site. After the injection, the patient will likely be taken to a recovery room where they will be monitored for up to an hour.
Following this the patient will be allowed to leave. It is normal to have some mild drowsiness, and numbness, tingling or weakness in the legs for the remainder of the day. These symptoms will gradually wear off be the end of the day. Epidural Steroid Injection Risks.
Epidural steroid injections are generally very safe, but there are some rare potential complications. One of the most common risks is for the needle to go too deep and cause a hole in the dura, the tissue that surrounds the spinal cord and nerve roots. When this occurs spinal fluid can leak out through the hole and cause a headache. This headache can be treated with bedrest, or with a blood patch. A blood patch involves drawing some blood from the vein and the injecting it over the hole in the dura.
The blood forms a seal over the hole and prevents any further fluid from leaking out. Rarely, a patient may develop an allergic reaction to one of the medications injected. This can cause itching, a drop in blood pressure , wheezing, or swelling. If the needle touches the spinal cord or nerve root it can cause a neurologic injury. This most commonly causes a temporary feeling of numbness or tingling in the extremities. When to Seek Medical Care.
You should seek medical care after an epidural injection if you develop any of the symptoms described above including headache , dizziness , increased pain, numbness or tingling, trouble breathing, or a skin reaction. The patient will typically make a follow-up appointment after the epidural steroid injection. This will likely be between two and six weeks after the injection to determine how the patient has responded to the injection and if they have any continued symptoms from the nerve compression.
If the patient continues to have symptoms or if they return after a period of time they may consider having the injection repeated. Most physicians recommend no more than injections during a year. The outlook for epidural steroid injections is very good.
Most people who receive the injection obtain some improvement in their symptoms. Further research is being conducted to help doctors determine who will benefit most from epidural steroid injections.
