Lumbar Epidural Steroid Injection (LESI)

A lumbar epidural steroid injection (ESI) is a minimally invasive procedure used to relieve lower back pain and leg pain (sciatica).

This treatment involves injecting a powerful anti-inflammatory steroid medication into the epidural space around the spinal nerves in the lower back.

The goal is to reduce inflammation, relieve nerve irritation, and decrease pain, helping patients return to normal activities.

What Conditions Does This Treatment Help?

Lumbar epidural steroid injections are commonly used to treat:

How Does a Lumbar Epidural Steroid Injection Work?

Pain in the lower back often occurs when spinal nerves become inflamed or compressed.

  • The steroid is injected into the epidural space around the nerves
  • It reduces inflammation and swelling
  • This relieves pressure on the nerves
  • Pain signals traveling to the brain are reduced

This allows the irritated nerve to heal and function more normally.

What to Expect During the Procedure

Before the Procedure
  • Review of symptoms and imaging (MRI or CT scan)
  • Adjustment of medications if needed
During the Procedure
  • Performed under fluoroscopy (X-ray guidance) for accuracy
  • Local anesthesia is used to numb the area
  • A needle is guided into the epidural space
  • Steroid medication is injected near the affected nerve
  • Procedure typically takes 15–30 minutes
After the Procedure
  • Short observation period
  • Mild soreness may occur
  • Most patients go home the same day

Benefits of Lumbar Epidural Steroid Injection

✔ Minimally invasive, no surgery required
✔ Reduces inflammation and nerve irritation
✔ Provides relief from back and leg pain (sciatica)
✔ Improves ability to participate in physical therapy
✔ May delay or avoid surgery

Many patients experience temporary but meaningful pain relief, often lasting several weeks to months.

Who Is a Good Candidate?

You may be a candidate if you:

  • Have lower back pain with leg pain, numbness, or tingling
  • Have nerve compression confirmed on imaging
  • Have not improved with medications or physical therapy
  • Want a non-surgical treatment option

This procedure is commonly recommended before considering surgery.

Risks & Side Effects

Lumbar epidural steroid injections are generally safe, but possible risks include:
  • Temporary increase in pain
  • Headache (due to spinal fluid leak)
  • Infection or bleeding (rare)
  • Nerve injury (very rare)
  • Temporary increase in blood sugar or blood pressure
Serious complications are uncommon when performed by experienced specialists.

When Is This Treatment Recommended?

Lumbar epidural steroid injections are typically recommended when:
  • Conservative treatments have failed
  • Pain is nerve-related (radicular pain or sciatica)
  • Symptoms are affecting mobility and quality of life
  • Surgery is not yet necessary
👉 It is considered a key intermediate step before advanced procedures or surgery

Recovery & Results

  • Pain may initially worsen for 1–2 days before improving
  • Relief usually begins within 2–7 days
  • Pain relief may last weeks to several months
  • Repeat injections may be recommended if needed
This treatment often helps patients resume daily activities and rehabilitation programs.

FAQs

Most patients feel only mild discomfort due to local anesthesia.
Relief may last from weeks to several months depending on the condition.

Typically limited to a few per year for safety.

No, but it can provide significant temporary relief and guide further treatment.

FAQs

A LESI is a common procedure where medications, usually steroids, are injected into the epidural space of the lumbar spine to calm inflamed nerves.

The steroids injected into the epidural space help calm down inflamed nerves that may be causing low back and leg pain.

The procedure usually does not require sedation, but patients are given a local anesthetic to reduce discomfort from the needle.

LESI is used to treat lower back pain and pain that radiates to the legs, including radiculopathy, radiculitis, spinal stenosis, degenerative disc disease, herniated discs, and post-herpetic neuralgia.

Post-herpetic neuralgia is a complication of shingles, and LESI is used as one of the treatments for this condition.

A needle is used to access the epidural space, and medications such as steroids are injected to reduce inflammation.
