Do you need a referral for a nerve root block?

A nerve root block is an image-guided injection placed near a spinal nerve root. A pain specialist or spine clinician may use it to help identify whether an irritated nerve is contributing to pain and, in selected cases, to reduce inflammation around that nerve. The clinician needs your symptoms, examination findings, medicines, allergies, and relevant scans before deciding whether the procedure is suitable.

Ask the clinic whether self-booking is accepted or whether it requires a referral from a general practitioner, orthopaedic surgeon, neurologist, or physiotherapist. Bring scan reports, a list of medicines, and details of previous treatments. Tell the team if you take blood-thinning medicine, have an infection, or could be pregnant, because these details can affect preparation and timing. A referral does not by itself mean the injection is the right treatment.

Seek urgent medical assessment for new loss of bladder or bowel control, numbness around the groin, rapidly worsening leg weakness, or severe back pain after major trauma. These warning signs need prompt evaluation rather than waiting for an injection appointment. Fever with severe back pain, or a new progressive neurological problem, also warrants urgent contact with a medical service.

Ask who should refer you, what records the specialist needs, which medicines require review, what benefit the block is intended to provide, and what alternatives are available if it is not appropriate.
