What these procedures actually feel like

WHAT IT FEELS LIKE

Most of these procedures feel like a few seconds of sting from the skin anesthetic, then pressure rather than sharpness. You stay awake so you can tell us what changed. Radiofrequency ablation carries the most sensation, and discography is designed to provoke your pain.

Nobody asks this in the room, and almost everybody wants to know. So here it is, procedure by procedure. We leave out the kind of reassurance that makes people trust the answer less.

Are you awake for a neck injection?

Everything we do is done with you awake and able to talk, under local anesthetic, with no sedation. That is not a cost-saving decision, and it is not stoicism. A block is a question put to a specific structure. The answer is you telling us what changed. Sedate that away, and you have performed the procedure but lost the information it existed to produce.

There is trial evidence on exactly this in the transforaminal epidural setting. Adding sedation changes reported pain scores in a way that muddies the diagnostic read. For a diagnostic injection, it defeats the purpose. We use no sedation for any of them, and most patients drive themselves home.

The other half of the reason is safety. A needle near a nerve root is safer when the person attached to the nerve can say “that went down my arm.”

Does a neck injection hurt?

• Medial branch block. Local anesthetic in the skin first, which stings for a few seconds. After that, pressure rather than sharpness. Two or three small nerves per level, a few minutes in total. Most people are surprised it is over. The block is a test, not a treatment, which is why it is short.
• Cervical epidural. The same skin anesthetic, then a deeper pressure feeling. Occasionally your usual arm symptom is briefly brought on as the space is entered. That is useful rather than alarming. It is delivered to a level, not to a neck.
• Occipital nerve block. Among the quicker ones. A small volume goes in at the base of the skull. Afterward, the scalp is numb for a few hours. People rarely expect that, and occasionally find it stranger than the injection. It answers a diagnostic question the same day.
• Radiofrequency ablation. The longest of them, and the one with the most sensation. Test stimulation comes first. That is a buzzing or tapping you will be asked to describe. Then comes the lesion itself, under local anesthetic. Aching for a few days afterward is normal. The nerves regrow, which is the deal nobody explains up front.
• Discography. The one we are most honest about, because it is designed to provoke. The question is whether pressurizing a given disc brings on your pain. So a positive result hurts. It is the only test that asks a disc directly, and it is not ordered casually.

Does an EMG or nerve conduction study hurt?

Nerve conduction studies and EMG have a worse reputation than they deserve. The published work on tolerability (how well people handle them) is reassuring. The studies are safe. People consistently rate the discomfort lower afterward than they expected beforehand.

Two halves. The conduction half delivers brief electrical pulses. They are startling rather than painful, like a static shock you can see coming. The needle half uses a fine wire electrode in several muscles. It is held still while you contract gently. It aches. It does not require anesthetic, and it takes a few seconds per muscle.

Anticipation is doing most of the work here, and that is not a dismissal. Trial data on procedural anxiety shows that simply describing what is about to happen lowers both anxiety and reported pain. That is the entire reason this page exists.

What are the side effects of a steroid injection in the neck?

Corticosteroid injections are well characterized (well studied). In trained hands, the serious complication rates are low. The common effects are a sore site for a day or two, a few days of flushing or disturbed sleep, and a short-lived rise in blood glucose. That rise matters if you are diabetic, and it is discussed beforehand if you are.

We are not going to inflate that into a warning block. And we are not going to pretend it is nothing. It is a short list, it is known, and you should hear it before rather than after.

What we ask of you

Tell us during, not afterward. If something brings on your symptom, say so at that moment. That is the data. If something is unpleasant in a way you did not expect, say that too, because almost everything can be adjusted. Nothing is done on the first visit, so you will have met us and seen the room before any of this applies to you.

Frequently asked questions

How long does it take to recover from a neck injection?

After a steroid injection, the most common effect is a sore injection site for a day or two. Some people also have a few days of flushing or disturbed sleep, or a short rise in blood sugar, which matters if you are diabetic. Radiofrequency ablation leaves an ache for a few days, which is normal. After an occipital nerve block, the scalp can feel numb for a few hours.

Is it normal to feel my arm pain during a cervical epidural?

It can happen, and it is useful rather than alarming. As the needle enters the epidural space, some people feel a brief return of their usual arm symptom. Say so at that moment. Being awake and able to report that sensation is part of what makes a needle near a nerve root safer.

Does radiofrequency ablation hurt?

It is the longest of the neck procedures and the one with the most sensation. First comes test stimulation, a buzzing or tapping feeling you will be asked to describe. The treatment itself is done under local anesthetic. Aching for a few days afterward is normal. The treated nerves regrow over time, which is worth knowing before you start.

Why is discography painful?

Because it is designed to be. Discography asks whether putting pressure on one particular disc brings on your own pain. So a positive result hurts by definition. It is the only test that asks a disc that question directly, and it is not ordered casually.
