Persistent femoral nerve pain

by Alex
(London, England)

Hello. I have a long history of lower back problems, with 3 bulging discs in the lower region. I had gone several years without a bad spasm and was being fairly good about my core strength exercies.

In mid-March I suddenly developed severe pain in the right thigh, running down to the knee.
An MRI showed a 'right paracentral L3/4 disc prolapse' causing a 'stenosis of the traversing L4 nerve root as well as the exiting L3 nerve root'. (Quotes from my consultant's letter.) Another letter mentioned a sequestrated disc.

The cause has been put down to routine 49-year-old wear and tear, not helped by sitting at a desk in the office for up to 11 hours a day for a couple of years.

On March 20 I was given epidural anti-inflammatories, tranformaninal and facet joint injections, which cleared up 60% of the pain. Five weeks later however the pain was returning though not nearly to the same degree. The consultant surgeon recommended a second round of injections, which did little to help. In fact gradually the pain worsened in the weeks afterwards.

On May 22 the pain had increased to the point that I went home from work with strong pain in the groin and bad ache in the thigh.
I have been off work since. I have been doing physio to strengthen the quads and core muscles, and floss the nerve. I take two half-hour walks each day.

But it's now ten weeks off work and I still can't sit for more than 20 mintues wihtout needing to get up. I can't be on my feet for more than 2 hours without needing to lie down to relieve the pain or ache in the groin.

What do to next? I've got to get on with my life and can't stay off work forever. I would love not to miss a holiday to Greece booked for Aug 17.
The surgeon has left it up to me to choose between doing nothing, a third set of injections, or decompression surgery. He is not pushing surgery.

I am inclined to try a third injection ASAP, and make sure to resume physio right away afterwards, which I didn't do after the first two injections. Your thoughts would be much appreciated.

Hello Alex,
I seem to remember answering this, but let's have another go. I know exactly where you are, because last year I was in precisely the same position, with almost identical MRI findings. You can read about it at femoral nerve damage using the site search function at C-H.

Who ever called this "routine" is nuts; you have an extremely painful condition; I know!

In my case, two things were different; first I'm a chiropractor and knew exactly what was happening. And secondly my daughter is a chiropractor; this is a very serious condition, often ends up in surgery, but because two educated and committed minds were working together I recovered.

Yours is going to be more difficult now, because so long has passed. What we worked out was that the usual "lumbar roll" treatment increased the pain, but a side posture technique lying on one side only, with a gentle thrust on L3, specifically NOT trying to get a release is what fixed it.

But I did stop completely for about 2-3 weeks and was then extremely careful for several months. Within two weeks the pain in my leg was virtually gone, but the numbness and weakness around the knee took nearly six months to recover. We are now at one year, and I'm absolutely fine.

Could you recover completely like this after all these months? I'm not sure. Gather up your scans and x-rays, and start hunting for an experienced and thorough chiropractor close by. Perhaps print this out for him or her; they are welcome to contact me.

Let me know how you get on.

Numbness in outer thigh following lunge exercise
by: Brian

Having recently lost over 100 lbs in weight and with no other medical issues I have started training with a personal trainer and whilst doing a lunge move where my left knee was close to the floor whist the right foot was extended in front of my body a shooting pain went through my outer left thigh and went as quickly as it happened with soreness and a little after pain. Now my outer left leg around the quad is numb. Any suggestions on how to aid recovery would be gratefully accepted.

Dr. Barrie Lewis Dr. Barrie Lewis

Hello Brian, congratulations on the weight loss; I take you've done it deliberately with dieting of some sort. There will be enormous benefits down the road.

Take your exercise routine slowly; you ain't gonna make the Rio Olympics! It seems you trainer may have pushed you a little too hard.

The first thing to watch for is whether the knee starts to give; that's serious as it means an injured femoral nerve most likely.

If it's only sensory, then we suspect a problem with the Lateral Femoral cutaneous nerve; it has no motor component and when irritated affects the outer thigh.

The condition is called meralgia paresthetica; it's a double crush syndrome with the nerve being irritated in the mid lumbar spine AND the groin; both have to be addressed for a successful outcome.

I would recommend stopping everything for a couple weeks and just doing a few gentle home exercises; mostly likely it will resolve on its own. Do some walking and perhaps swimming and cycling for a month.

If it doesn't then a professional examination is called for to determine the cause of your problem.

I hope this contributes; let me know how you get on.

what type of swimming?
by: Anonymous

Dr B,
thanks for your previous comment. I encouraged my physio to try and manipulate gently and it has been helpful. Neural flossing, she called it. A couple of days on and the groin pain has reduced and my sitting down time has extended to half an hour or so.
Could I ask another question? Which swimming styles/exercises were helpful to you with this problem? I know to avoid breast stroke.

best regards,

Dr. Barrie Lewis Dr. Barrie Lewis

Hello Alex,
I would suggest butterfly. Only kidding!

Start by just lying on your back and kicking gently; use your arms if you want. Do that for a week or two. Then you might tentatively try some crawl.

response to Dr B
by: Alex in London

Many thanks for your comments. I did visit one of the best osteopaths in London but he was wary of aggravating the nerve pain, and did little.
I will show him the manipulation your daughter found successful.
But if I cannot find an osteo or chiropracter here to deal with this, my dilemma is going to be choosing between an operation or letting it run its course with exercises, careful lifestyle etc... The physio estimates a 5-11 month recovery period but I don't know if I can face that much longer living this semi-life and dealing with constant niggles or pain. Any thoughts you have on that choice would be much appreciated.
As for sleeping, I am on my back or side.

Hello Alex,
There is risk with all treatment, including chiropractic; but my questions is, can it actually be made worse? You're headed for an operation anyway to remove the fragment pressing on the nerve.

There's a big difference between medical and chiropractic treatment; they consider this an inflammation, we consider it something physical pressing on the nerve. Like we wouldn't treat a broken arm with anti inflammatories.

The question is whether the offending disc fragment can be displaced with skillful, artful manipulation? I believe it can; as I said I personally had this exact problem.

That traction device is worth a consideration; it has merit but I've only used it once on a condition like yours and it made it worse, but that's simply an anecdote. I decided not to use it myself; the manipulation was sufficiently effective that I didn't need to risk it.

There are various decompression tables, using traction that have merit too.

It takes quite a lot of courage for a chiropractor to wade into a back like yours. I do it pretty confidently now, but I've been in this business for 34 years. Artfully done, there's much to be gained; brutally done there's much to be lost! But you're heading for an op anyway.

Look for a chiro in your area who is experienced; and courageous!

Try Inversion Table for Lower Back
by: Anonymous

Hi Alex:

The most effective treatment I have found, for what you are describing, is to slowly reverse the 49 years of standing and sitting by hanging upside down on an inversion table, to reverse the effects of gravity. I do my Inversion Table for 10 minutes in the morning, and again in the evening. Doing so, gives me mobility for the whole 12 hours, and it is a drug free do-it-yourself treatment.

The table I recommend is the Iron Man ATIS-4000, which sells for about $300 in WalMart in Canada and America. Check it out on the web, look at the specs (like locking lever for the inversion angle, and secure foot clamps), then see if you can find something similar in the UK.

I think it might be worth a try in your situation, because it has really helped me. The instructions will recommend you slowly invert over a two minute period in order to allow the blood pressure to equalize as you go upside down. Same thing coming right way up again. Unless you have a severe heart condition, there does not appear to be any danger for 10 minutes of inversion.

Best wishes.
Garry Anderson.

Thanks for this Garry.

Do you lie on your back or stomach?
