A cervical nerve root injection places medication close to an irritated nerve in the neck. It may be considered when nerve compression causes pain travelling into an arm.
What is the purpose?
The local anaesthetic may provide short-term relief, while the steroid aims to reduce inflammation. The goal is mainly to improve arm symptoms. The response varies, and an injection cannot remove a disc or bone spur.
What happens?
You will be asked to lie on your back while a fine needle is guided into the side of your neck. X-ray imaging and contrast are used to check needle position before medication is given. A non-particulate steroid is used to make the procedure as safe as possible. You are monitored before going home.
What are the alternatives and risks?
Alternatives include medication, physiotherapy and, in selected cases, surgery. Temporary pain flare, soreness, faintness or altered arm sensation can occur. Infection and bleeding are uncommon. Serious neurological injury, including stroke, is a rare but important risk that must be discussed as part of consent.
