Injection for radiating back pain

What is it?

What is it?

Due to wear and tear (arthrosis), inflammation, surgery or an accident, the spinal column may undergo changes, which may lead to ‘nerve pain’. This causes pressure on, or irritation of, the nerves. Depending on which nerve is irritated, the pain will radiate towards a certain part of the body, such as the back side of the thigh and down towards the ankle, or along the back side of the bone down towards the sole of the foot.

A transforaminal epidural injection may help you in this case. It is an injection given with local anaesthetic and an inflammation inhibitor (cortisone) in the epidural space, which is located around the spinal cord.

The goal is to address the nerve inflammation, which will reduce the pain and have you back to being active more quickly.
