Epidural Injections

Epidural Injections

The epidural space is located inside your spinal canal, between the dural sac (a protective layer surrounding your spinal cord) and the bones of your spine. This space contains fat, blood vessels, and nerves. Sometimes, these nerves can become compressed or irritated, leading to pain and inflammation. This can happen due to several reasons, such as:

• A herniated disc pushing into the epidural space
• Spinal stenosis, a narrowing of the spinal canal
• Degeneration of the discs and joints in your spine over time

How the Procedure Works

1. You’ll lie face down on an exam table.
2. The injection site is cleaned and sterilized.
3. A local anesthetic is used to numb the area.
4. Using X-ray guidance, the doctor inserts a needle into the epidural space.
5. A contrast dye is injected to confirm correct needle placement.
6. Then, the steroid medication is delivered through the needle.
7. The needle is removed, and the area is covered with a sterile bandage.

The steroids used in the injection help reduce nerve inflammation, which can ease pain.

Risks and Side Effects

As with any medical procedure, there are some risks, although they are generally low:

• Infection (rare, less than 1%)
• Dural puncture, which can lead to a temporary headache (about 50% of cases)
• Bleeding, more likely in people with bleeding disorders
• Nerve damage, which is extremely rare

Possible side effects may include:

• Headaches
• Anxiety
• Facial flushing
• Trouble sleeping
• Pain at the injection site
• Fever
• Stomach ulcers
• Cataracts
• Elevated blood sugar
• Weakened immune response
