Epidural Nerve Root Block Injection - A Personal Experience

Nerve-root injections for relief of sciatica - a personal account

I had an MRI scan last June which revealed that I have 2 herniated discs one on top of the other.

For over 18 months I had been suffering from severe sciatica. My doctor had originally suggested physiotherapy but the physiotherapist read my MRI results and said I was wasting my time with this treatment until I got some good pain relief sorted out.

After a year of taking paracetamol and ibruprofen, I was prescribed Amytriptyline, an anti-depressant which, when given at low doses (10mg) acts as a muscle relaxant.

It does offer some relief for pain at night and helps you to sleep but it didn't work for me and I had it prescribed again at 25mg and finally started to get some sleep - but I woke every morning feeling like I had a hangover, which wasn't very nice when I had to be at work at 8am.

My sciatic nerve pain was in my back, my right buttock, my right leg and my right foot, pain was especially bad in my right calf and both hips. By the time of my MRI scan I had already had 12 months of severe pain.

I was suffering from what is usually referred to as sciatica and this was being caused by the 2 herniated discs at L4 & L5 at the base of my spine impingeing and presing down on my sciatic nerves.

Sometimes, sciatica might only last a day or two but on other occasions it can last for years. Thankfully, sciatic nerve root injections are a good way to achieve pain relief.

Sciatica itself is not an illness in its own right, it is always a symptom of underlying spinal problems.

Usually sciatica is symptomatic of injury to the spine.

Physiotherapy is often the first choice of treatment beofre nerve-root injections or surgery are offered.

Choices? Physiotherapy is an option

Initially, I opted for physiotherapy but with only limited success. I had a short pain-free period but the pain started again and this led me to see a neurosurgeon to determine the best course of action to get me out of pain. I should say that physiotherapy works for many people without any further action required. I just wasn't one of them!

After Physiotherapy Doesn't Work - Nerve Root Injection or Surgery?

I was offered a choice of surgery or nerve-root block injections.

Now whilst the latter sounds pretty awful, I decided that if I could delay surgery then I would.

I had the nerve-root injection into the nerve-root between lumbar 4 & lumbar 5.

Nerve-root block injections contain a mixture of local anaesthetic and steroid.

The anaesthetic numbs the nerve completely, whilst the steroid acts as a strong anti-inflammatory.

Do Some Research - Use the Internet

I went on the internet the week before just so I knew what to expect. The very idea of someone injecting a syringe into my spine gave me the shivers.

Unfortunately, there wasn’t a lot of information out there. It was all very brief and I was worried about whether it would be a painful procedure.

Bear in mind that I have now endured 17 months of sustained pain, unable to sleep without taking drugs. I still can’t lift anything heavy or bend forward.

Anything that would give me some relief from the pain was worth trying though although I headed for the hospital with some trepidation, I also did so hoping that I would soon be pain free (on my right side anyway).

Nerve-Root Block Injection - The Process

  1. MRSA Swabs – you will be asked to do depending on which hospital you are going to. I had a swab taken from my throat, nostril and groin (don't worry you do this all yourself - not invasive at all).
  2. I was then interviewed by the neurosurgeon who would carry out the injection. She explained exactly what she would do, The whole procedure would be done in the X-Ray room. She would be x-raying my back in real-time. This way she could guide the injection with accuracy into the nerve root.
  3. I would be given a number of local anaesthetics. These would feel like a sting but were necessary to carry out the nerve-root injection.
  4. The procedure would take about 15 minutes.
  5. My leg might go numb or tingly shortly after the nerve-root block injection.
  6. And finally, for some people the nerve settled down completely after a nerve-root block injection but some people might only get a few weeks or a few months relief before the pain returned. If this happened, surgery was the next course of action.

She then asked me which side of my back was worse. I said ‘right’ and she drew a symbol on the right hand side of my back.

In the X-Ray Room

You are asked to lie on your tummy on the bed. The X-Ray screen is beside you though you can’t see it as you will be resting your head on your arms in front of you.

The neurosurgeon will tell you that she is taking a ‘bearing’ based on the X-Ray. She will then draw lines on your back which she will use as a guide to exactly where she needs to inject.

She will then tell you that she is going to inject you with local anaesthetic into the area.

For me, this was no worse than a sharp nip a few times. I got a short pain in my right buttock but I think this was caused by my own nervous tension more than the anaesthetic.

After about five minutes, the neurosurgeon told me she was administering the nerve-root block injection and that I may sense some numbness or tingling but should experience no pain during the injection. She also told me that if I was in any pain, she would stop.

Thankfully, I suffered only a small amount of pain when she withdrew the needle but nothing too dreadful; just another sharp pain in my right buttock.

I was helped up from the bed and asked to sit on the side of the bed until I was ready to get up.

The tingling sensation lasts for about 5 minutes and you will be a little bit shaky (from nerves probably). I had to be accompanied for the procedure (though your +1 will not go into the X-Ray room with you) because you must travel home with someone and not use public transport (though I used a cab).

I was well enough to return to work the next day.

And so far, so good – my right side has felt a bit easier. The neurosurgeon told me I should notice some real relief within 10 days. The anti-inflammatory is a slow release drug, it is meant to last a while. I am hoping the sciatic nerve settled down enough to not give me any pain in the future.

I think keeping on top of pain is an important part of managing severe sciatic pain. Using a balm like Outback or Penetrex or even a natural pain reliever like Pernaton (made from green lipped muscles) can help you to get on with life whilst you are awaiting your nerve root block injection.

I still do some exercises taught to me by my physio (these are all available with instruction on YouTube if you look carefully enough) if I get a twinge but as I write this in 2017, I have been sciatica free for four years now and I would not hesitate to recommend the procedure to those in discomfort from back pain - for me it's been life-changing.

Sciatic Nerve Root Block Injection - A Personal Experience Comments

Nancy Ball on March 31, 2018:

I’m with Daisy, below. A nerve block in my neck, yesterday, was described as feeling like

bee stings, followed by a sense of pressure. Being basically brave, I thus chose the

“local”. The good news? It didn’t last long. The bad news? The pain was EXCRUTIATING! (Further bad news? I haven’t seen any relief yet. Not happy here...

Coni on April 17, 2014:

I am scheduled for this procedure next week and my anxiety levels are through the roof! I have sensory neuropathy in my right leg, hence the pain I feel is transformed into the proverbial "pins & needles" x5 effect! I mostly feel the pain in my right buttocks, but as it travels down my nerve impulses get all mis-wired! Thank you for posting this as it has helped to ease my fears...but I'm still scared!

TheWinKing from South Africa on September 13, 2012:

Thanks for this great piece. My friend was recently diagnosed with herniated discs and she is struggling a bit. She has just tried Bowen therapy, which as far as I understand is a mild form of physiotherapy. She said this has helped her with the pain, but I will be sending her this hub as a reference in case it stops helping.

Jools Hogg (author) from North-East UK on September 13, 2012:

MPG, Glad you got some relief as well. I spoke to lots of people who told me not to get it done, saying it would be agonising etc but it was not anywhere near as bad as I was led to believe, in fact I would have it done again if needed.

Jools Hogg (author) from North-East UK on September 13, 2012:

Nell, many thanks for your comment. Mine started completely out of the blue - I went for a walk one tea-time with a friend and woke up the next day with a bad back; it's been bad since that time - 2 herniated discs, what a pain (literally) :o)

Maria Giunta from Sydney, Australia on September 12, 2012:

Oh how I feel your pain Jools99. I too had this injection only a few months ago after seeing a neurosurgeon who said an operation was not an option. Like you the injection relieved my severe pain and I am now sleeping and moving better. Good luck with staying out of pain. Voted up and useful.

Nell Rose from England on September 12, 2012:

From someone who suffers sciatica quite a lot I feel for you! ouch! I am glad that you got the injections, hopefully this will work, if only for a few months the relief will be amazing. Mine is caused by my back just sitting on the sciatic nerve for hours on end at work started it off, and its so painful, as you very well know! great explanation that will be a great help for people, voted up!

Jools Hogg (author) from North-East UK on September 12, 2012:

Mary, thanks so much for your comment. All I can say is good for you that your back has never troubled you - it's a blummin' pain :o(

Mary Hyatt from Florida on September 12, 2012:

I feel bad for anyone who has back pain. Fortunately, I have never experienced back pain, don't know why...just lucky I guess.

I voted this Hub up, and will share in the right places.

Jools Hogg (author) from North-East UK on September 12, 2012:

Janine, thanks for your comment,pin, tweet and share. I woke up with sciatica after going for a walk the night before, just like that. The nerve root injection has given me a full year of relief and is still about 70% better than it was last June. I am learning to live with sciatica and I now know what I can and can't manage. Your chiroptractor will certainly be helping, I wish you well and hope it improves soon.

Janine Huldie from New York, New York on September 12, 2012:

Wow, why have I not seen this article before. Julie thank you so much fro sharing your story here about your issues with Sciatica. I too have had problems with this ever since having my second child and go to a chiropractor once a week for treatments. I have actually been doing better, but still have had flareups from time to time. I have pinned your article to reference and ask my doctor about this and have also voted, shared and tweeted too!!

Jools Hogg (author) from North-East UK on September 12, 2012:

Jaye- many thanks for stopping by. I'm so sorry that you got no relief from the injections, taking drugs all day every day starts to get you down doesn't it? They did tell me it could fail but luckily , it didn't though I am starting to get pain back in that area again now so may get another injection soon. I'm trying to put off the surgery to be honest.

Jaye Denman from Deep South, USA on September 12, 2012:

I'm so glad this worked for you and hope the pain relief lasts. I've tried the injections twice, with no discernible difference, but I know they help a lot of people.

Jools Hogg (author) from North-East UK on September 12, 2012:

Audrey, many thanks for the visit and the share :o)

Jools Hogg (author) from North-East UK on September 12, 2012:

Daisy - thanks too for your MRI link which I used in this hub :o) Thanks for your comment. To be honest, I went into that x-ray room pretty scared but by then I was desperate for some pain relief so when it turned out to be a pretty painless thing, I was relieved but also optimistic that I'd feel better. Hope your neck got better.

Audrey Howitt from California on September 12, 2012:

Ouch! And yet I can see how this would help--what a great explanation Jools! Sharing!

Daisy Mariposa from Orange County (Southern California) on September 12, 2012:


Thanks for explaining this *painful* subject in such an easy-to-understand manner.

I once had to have an injection in my neck for pain due to an injury. It wasn't a pleasant experience at all.
