What is a Transforaminal Epidural Injection?
A Transforaminal Epidural Injection is an advanced procedure that involves injecting anti-inflammatory medication directly into the epidural space near the affected nerve. The injection targets pain relief at the precise site of nerve irritation, providing targeted treatment. According to NHS, this procedure can be highly effective for conditions such as disc prolapse, slip disc with sciatica and lumbar radiculopathy.
When Is a Transforaminal Epidural Injection Recommended?
This injection may help when a disc herniation or narrowing of the spine causes sciatica or radiating leg pain, especially when these symptoms do not settle with conservative care. It is particularly effective for targeting the affected nerve root. Dr. Purnajyoti Banerjee, a leading consultant in the field, performs Transforaminal Epidural Injections under X-ray guidance in London.
Conditions Treated by a Transforaminal Epidural Injection

What Happens During a Transforaminal Epidural Injection?
BEFORE
You can eat and drink normally unless sedation is planned. Arrive 30 minutes early for consent.
DURING
Lying face-down with the skin numbed, X-ray guidance and contrast confirm the needle position at the nerve’s exit point before medication is delivered. Most patients feel pressure rather than pain.
AFTER
You rest for a short period and go home the same day with a companion. Leg symptoms may ease over the following days as the medication takes effect.
