Meralgia Paresthetica

Meralgia paresthetica causes numbness and sometimes a stinging upper thigh pain, usually on the side above the knee.

This condition is caused by a trapped nerve in the groin causing pain classically on the side of the thigh, but also sometimes the front of the upper leg.

The trapped fibres are from the Lateral Femoral Cutaneous Nerve. It originates from the upper lumbar spine, L2 and L3, meanders down a large muscle deep in the belly called the psoas, crosses another in the pelvis called the iliacus, and then is trapped as it passes under the inguinal ligament.

There is usually no acute low back pain, though there may be a dull ache in the upper lumbar spine. Fixations are usually found here by your chiropractor and in our opinion are a large part of the problem.

But, with groin pain, various impingement problems in the hip should also be considered. Conditions like Femoro acetabular impingement syndrome in the younger person, progress to hip arthritis in the older patient.

Upper thigh pain

Upper thigh pain occurs but in varying patterns depending on which of the little slips of the femoral nerve is affected. Is the numbness on the side or front, in or below the groin? Is it stinging in the buttock? Meralgia paresthetica classically affects the lateral thigh.

Often there is an upper lumbar thigh pain connection.

Meralgia Paresthetica

Meralgia paresthetica is what we call a double crush syndrome; like the carpal tunnel where the median nerve is trapped, often in several places somewhere in the neck, shoulder, forearm and the wrist.

The result is the same; a burning, nerve type pain in the thigh, with minimal back pain.

Classically the pain is on the outer side of the thigh, but because the femoral nerve has so many small off shoots, variants may be in the groin and front of the leg, and even the labia.

Whilst these are not true meralgia paresthetica, to all intents and purposes the result is the same, only the pain is in the front of the thigh. Here your chiropractor will be even more careful however, as the femoral nerve is motor as well as sensory; you may start to get weakness of the quadriceps, the large four part muscle on top of the upper leg.

If you hop on that leg, does it tend to give? Report it immediately.

Your chiropractor will do a test which stretches the femoral nerve, and it's likely to cause much pain in the front of your thigh.

In the above graphic, can you trace both the lateral femoral cutaneous n. with side of the thigh pain, and the femoral nerve which would affect the anterior upper leg, as they make their way through the groin?

Extreme tenderness in the groin

If you run your thumb down through the muscles of the anterior thigh (careful, you may cross the Femoral artery pulsating under you finger, avoid it) you are likely to encounter extreme, and I mean extreme tenderness in the groin of one or more muscles. However, this is not always the case.

Most syndromes come in variant forms. Diabetes may cause you to go blind and a toe might go black and fall off, but that isn't always the case fortunately. Follow the diabetes rules, and you can live to a healthy eighty with your eyesight and ten toes intact.

Likewise with Meralgia Paresthetica, follow the rules, and this too will pass.

Part of the treatment is to address those extremely painful muscles in the groin; chiropractic care is not usually particularly uncomfortable, but this really does hurt for about thirty seconds, and may leave some bruising.

It's very rare, but sexual advances chiropractor do occur, so it's best to take a friend or partner with you.

Slipped disc symptoms

Some of these features may also occur in the so-called SLIPPED DISC SYMPTOMS ... the distinguishing "differential diagnostic" features being the lack of serious low back pain, and the extreme tenderness in the groin where the nerve is being pinched.

So too, no loss of refex or muscle weakness as the LFCN is not motor.

Complicating factors ...

Let it be said, this can be a very painful and serious condition. Mostly it is benign and well managed by your Chiropractor. However these nerves can be affected by an abscess in the Psoas muscle (are you feeling sick, running a temperature, history of TB?), by bowel tumours (have you lost weight? are your bowels working normally? has there been a change in your bowel habits?). If in doubt, also consult your physician.

Is the pain in your thigh brought on with exercise? Read this strange tale by chiropractor Bernard Preston. Intermittent claudication ...

  • So too should Lumbar Stenosis be considered.


    This is important: The Lateral Femoral Cutaneous Nerve is a sensory nerve. When irritated it does not cause specific muscle weakness in the leg.  However, if the femoral Nerve itself is affected, there may be Quadriceps weakness, and loss of the Knee jerk reflex. Plus sensory change in the skin of the upper leg and/or inner lower leg. Whilst Femoral nerve damage also responds to careful thorough chiropractic care, any specific weakness in the quad must be noted and monitored.
    In this short YouTube clip you can yourself determine if there's specific muscle weakness in your leg.


    Whilst meralgia paresthetica is not uncommon, it is fairly unusual that I am consulted in the same week by two women with severe meralgia paresthetica upper leg pain. Because it is a serious condition, I started treatment immediately, but also referred both patients to their doctors for xrays. Chiropractors cannot order xrays in the netherlands.

    After three treatments both were considerably improved, there was less pain in the leg and they were not unhappy.

    Mrs j continued to improve, and the pain and numbness was completely alleviated within about 6 to 8 weeks. She is a very satisfied patient and is coming in currently in every two months for a checkup.

    Mrs P's doctor decided this was far too serious a condition for a quack, and advised her to stop the treatment. After all he said, there is no known cure for meralgia paresthetica, which is quite true; there is no research confirming that there is any effective medical or chiropractic care. That was five months ago.

    Yesterday her daughter phoned to say her mother was going for a back operation. Did I miss something? Is it because medicine is just anti chiropractic? Was she over compliant to her doctor's overbearing demands?

    Frankly I don't know. What I can tell you is that chiropractors treat upper thigh pain with great confidence. Sure, if you have been losing weight, or are running night fevers, have a change in bowel habits, or if you're a heavy smoker then a second opinion is definitely on the cards.

    The first step of chiropractic help, of course, in the treatment of meralgia paresthetica is a proper history and examination to rule out other diseases. An aneurism in the pelvis caused by smoking; it really does knock ten years off your life, more if you are a woman, heart attack, tumours and the like really should be considered, though rarely do they cause meralgia paresthetica.

    Chiropractic care may include some or all of the following:

    1. A Chiropractic adjustment of any spinal or sacro-iliac fixations found. This is not normally painful.
    2. Deep massage of any trigger points found in the groin muscles. This may be extremely painful. You may develop bruising. Ice helps.
    3. Stretching of your spinal joint and the muscles. Not particularly painful.
    4. In the rehab phase some vigorous exercises. These may include exercises such as:

    Core muscle exercise

    This simple core muscle exercise should be done by EVERY low back sufferer before arising from bed EVERY morning. It only takes 60 seconds after all.

    Chiropractic help

    Chiropractic help treatment programme for meralgia paresthetica would probably cover a 6-8 week period, with perhaps 10-15 treatments. Every person obviously is different. Some may require less, other more. Talk honestly to your DC.

    If after 3-4 weeks there is no definite progress then a medical consultation should be considered

    IlioTibial Band

    Another condition that needs to be considered when faced with lateral thigh pain is the Tensor Facia Muscle and its long tendon, the ITB, or iliotibial band; it runs from the pelvis down to the knee area.

    The definitive examination is called Noble's test... iliotibial band stretch

    Tingling in legs and feet

    Tingling in legs and feet will not extend to the lower leg with meralgia paresthetica. If you have tingling in legs and feet then your chiropractor will be considering a pinched sciatic or femoral nerve. This is more serious as they are mixed nerves, carrying motor impulses to the muscles.

    The key sign is that sciatic and femoral stretch tests will be positive, which is less likely with a pinched lateral femoral cutaneous nerve. Also reflexes will be affected.

    Interesting challenges of the day

    1. Mr S is a 76 year old man with neck pain of some 9 months duration. Luckily, most of the discomfort is upper cervical which is only rarely arthritic; his lower cervical spine is a degenerative mess that I have left alone. After seven treatments his pain and stiffness is 50 percent better, and he is happy in the circumstances. He can sleep through the night now and that makes a huge difference.

    2. Mr P is 32 year old man with very severe lower back pain radiating to the big toe which is 30 percent numb. He had an episode three weeks ago, took anti-inflammatories and was soon better as is typical of the medial disc herniation. But before it healed, after a trivia it came roaring back, much worse. The characteristic crossed sign was evident; sitting in a chair, straightening the right leg provoked severe left back pain and tingling in the leg. He is doing well.

    3. Severe lower back pain is scary; just ask Mrs P. Just watching her get out of the car I she was in trouble; she had a slipped disc at L4 making her lean towards the opposite side; luckily she had no pain in the leg. Despite family pressure that this was far too severe for a chiropractor, she persevered. Within five days she was standing upright, and after two weeks almost pain-free. 

    Despite a hectic job, she wisely took my advice and stayed home for what I call exercising bed rest.

    4. Mr S has had lower back, groin and back of thigh and calf pain for fourth months.

    He has a pincer deformity in the hip causing the stabs in the groin, and a degenerative facet causing the sciatica. Both are responding well to chiropractic and he is well pleased; sixty-five percent better after three treatments.

    5. Mr T is a wise man; he has taken a warning TIA seriously and has lost 15 pounds, and has at least as much again to lose. A change to a low starch diet and half hour daily stroll has made the difference; but the walking is making his foot and back miserable. The expensive orthotic is hopeless; luckily his hips and back are fine, but he needs a simple heel lift; he has a short leg.

    6. I too have had serious lower back issues, luckily fixed by my own chiropractor; so I too have to do my exercises, take care when lifting supers full of honey, gardening and using the chainsaw. Regaining the function of your spine is just as important as the pain.

    7. My own granddaughter, only 7 is hypermobile giving her pelvic, knee and ankle issues. X-rays show a mildly dysplastic hip. Years ago we would have called it growing pains. She too regularly needs chiropractic care and luckily responds well. Increased range of motion is more difficult than too stiff in my opinion. Our care is for kids too.

    8. This 65-year old lady is a serious gardener; every day she is bending, lifting and digging for 2 to 3 hours a day. It regularly catches her in the sacroiliac joint, so she has a treatment once a month that sorts it out. She does her lower back exercises faithfully.

    9. This 88-year old lady is an inspiration; every day she is busy in the community. With a nasty scoliosis she manages very well with a chiropractic adjustment every six weeks and exercises faithfully done. 

    10. Mr X is a 71-year old retired man who wants to continue with maintenance care every six to eight weeks; he had suffered from two years of lower back pain when he first came a few months ago. He has no discomfort now after 8 chiropractic treatments, but is aware that danger lurks.

    11. Mrs C has been having severe headaches, and taking a lot of analgesics. It is a non-complicated upper cervical facet syndrome, and she is doing well.

    12. Mr D is a 38-year old year man with chronic shoulder pain after a rotator cuff tear playing cricket. It responded well to treatment, but he knows he must do his exercises every day; for two years he could not sleep on that shoulder.

    13. Mr D, a 71-year old man, has a severe ache in the shoulder and midback since working above his head. Trapped nerve tests are negative but he has advanced degenerative joints of Luschka; after just two treatments he is 50 percent better. Can we reach 90?

    And so the day goes; chiropractors should not be treating the elderly most medical sites state but that is so much bunkum.

    Greetings, Dr B.

    You helped me quite some time back with a soothing and professional response which turned out to be exactly correct. I now consult a local chiropractor. You write a superb newsletter, too.

    Your own unresolved problem. Pose a question

    Knowing that up to 70 percent of the time the correct diagnosis is made with no examination, no special tests, no xrays, but just from the history, there is a fair chance I can add some insight to your unresolved problem. But at least 30% of the time, I may be quite wrong. Give plenty of detail if you want a sensible reply.

    You visited this chiropractic help site no doubt because you have a problem that is not resolving and want to know more about what a DC does.

    The quickest and most interesting way is to read one of my eBooks of anecdotes. Described by a reader as gems, both funny and healthful from the life and work of a chiropractor, you will love them. Priced right at $2.99, though Kindle fiddles the amount without telling me.
