What is it?

About this condition

Sciatica is pain that follows the sciatic nerve path — from the lower back down to the foot. Usually caused by compression of a nerve root due to disc herniation or stenosis, it can be treated very effectively without surgery through image-guided nerve blocks.

Common symptoms

How does it present?

  • Pain radiating from the lower back down the leg
  • Electric shock sensation, burning or numbness
  • Pain that worsens when sitting or walking
  • Weakness or difficulty moving the foot
  • Tingling in the leg or foot
  • Unilateral pain (usually on one side only)

Interventional approach

Treatment options

Each case is evaluated individually. The treatment plan is defined at the first appointment.

Nerve root block (TFESI)

Injection of corticosteroid and anesthetic at the compressed nerve root under fluoroscopy. Reduces inflammation directly at the source of pain.

Pulsed radiofrequency of nerve root

Modulates the signal of the compressed nerve without destroying it. An option when the block gives temporary relief but the sciatica recurs.

Caudal epidural block

Access to the epidural space via the caudal route to irrigate the entire lumbar area with anti-inflammatory medication.

Peridural neuroplasty

For sciatica caused by epidural fibrosis or adhesions that are post-surgical or long-standing.

Frequently asked questions

FAQ · Sciatica

Does sciatica always require surgery? +
No. More than 80% of sciatica cases improve without surgery. Interventional treatment is very effective as an alternative or prior step before considering surgery.
How many block sessions will I need? +
It depends on treatment response. Many patients get significant relief with 1 to 3 blocks. Response is evaluated before each session.
Is the nerve root block painful? +
The procedure is done under local anesthesia. There may be momentary discomfort, but most patients tolerate it well and leave walking.
How long does the block take to work? +
Relief can be immediate from the anesthetic, followed by 3–5 days for the anti-inflammatory to act fully.
