Epidural Steroid Injections

What is an Epidural
Steroid Injection?

Epidural steroid injection (ESI) is a minimally invasive procedure in which a corticosteroid medication and a local anesthetic are injected into the epidural space of the spine. The epidural space is the outermost part of the spinal canal and surrounds the spinal cord and nerves. ESI aims to reduce inflammation and relieve pain caused by various spinal conditions.

Conditions it Treats, Why You May Need It

Epidural steroid injections are commonly used to treat conditions such as herniated discs, spinal stenosis, degenerative disc disease, sciatica, and other conditions that cause nerve compression and inflammation in the spine. If you are experiencing persistent pain, weakness, or numbness in your back, legs, or arms due to spinal issues, your doctor may recommend ESI as a conservative treatment option before considering surgery.

How it Works: How it Will Help with Your Pain

The corticosteroid medication injected during the procedure helps to reduce inflammation and swelling around the affected nerves, providing pain relief. Additionally, the local anesthetic can provide immediate pain relief, though its effects are temporary. ESI can help alleviate pain, improve mobility, and enhance the overall quality of life for many patients.

What to Expect

• Procedure Duration: The procedure typically takes around 15 to 30 minutes, although this may vary depending on your specific case.
• Discomfort: Some patients may experience mild discomfort during the injection, but it is generally well-tolerated. Your comfort is a priority, and the medical team will take measures to ensure you are as comfortable as possible during the procedure.
• Risks: While epidural steroid injections are considered safe, as with any medical procedure, there are potential risks involved, including infection, bleeding, nerve damage, and a very small risk of allergic reaction to the medications used. However, serious complications are rare.
• Duration of Results: The duration of pain relief varies from patient to patient. Some individuals may experience relief for several weeks, while others may have longer-lasting effects. Repeat injections may be recommended if needed, but your doctor will develop a personalized treatment plan for you.
• Combination with Other Treatments: Epidural steroid injections can be used in combination with other conservative treatments, such as physical therapy, chiropractic care, and medication, to optimize pain relief and functional recovery.

Tips to Get Ready for the Epidural Steroid Injection Procedure

• Inform your doctor about any medical conditions, allergies, or medications you are taking.
• Arrange for someone to drive you home after the procedure, as you may experience temporary numbness and weakness in your legs.

What Happens During the Epidural Steroid Injection Procedure?

1. You will be asked to lie on an examination table, and the skin over the injection site will be cleaned and sterilized.
2. The doctor will use fluoroscopy (a type of X-ray) to guide the needle to the precise location in your epidural space.
3. Once the needle is in place, a contrast dye may be injected to ensure proper needle placement.
4. The corticosteroid medication and local anesthetic will then be injected into the epidural space.
5. The needle is carefully removed, and a bandage will be placed over the injection site.

Post-Operative Care

After the epidural steroid injection, you will be monitored for a short period before being discharged. It is essential to have someone drive you home after the procedure. You may experience some numbness or weakness in your legs temporarily. It’s normal to feel some relief immediately after the injection due to the local anesthetic, but the full effect of the corticosteroid may take a few days to a week to kick in.

• Take it easy for the rest of the day after the procedure.
• Avoid strenuous activities for the next 24 hours.
• Apply ice to the injection site if you experience any soreness.
• Keep track of your pain levels and any changes in symptoms to share with your doctor during follow-up appointments.
