The Sciatica Guide: Causes, Treatment and Solutions

Low back and leg pain usually get diagnosed with
Sciatica in 1 of 2 ways

1) Go to doctor and a diagnosis of sciatica is rendered.
2) Consulting Dr. Google searching for “causes of leg pain” and Sciatica #1

So naturally you must have sciatica…
But you’re properly wondering:
“What is Sciatica really and how do I how do I get my sciatic nerve to stop hurting?”

Hint : It’s NOT WHAT YOU THINK (2020 Update)

Ignore the standard montra…the Likely sciatica treatment is to use home stretching protocols….it doesn’t generally work.

Sciatica Meaning?

These terms can be confusing, but they basically mean the same thing for practical purposes. Sciatica by definition means a painful, inflamed sciatic nerve. When the sciatic nerve pain starts being noticed it’s referred to as sciatica.

Radiculopathy of the sciatic nerve implies that the sciatic nerve is being compression by a structure such as a herniated disc, thus creating sciatic nerve damage. This compression creates sciatic nerve pain, which is referred as sciatica.

“Pain down the back of the leg below the knee is the signature sign of Sciatica”

Anatomy of Sciatic Nerve

The sciatic nerve is the largest in diameter peripheral nerve (outside the spine) in the body. It originates from the nerves of the lower back. (L4-5), travels under the buttocks (gluteus maximus) and down the leg to the to the back of the knee.

Usually at this point (behind the knee) it divides into 2 branches (like a tree) into the tibial and peroneal nerve that travel to the foot.

Therefore, technically sciatica can be anywhere between the buttocks and the foot! So explains sciatica that makes you walk with a limp.

6 Major causes of Sciatica

1) Intervertebral Foreamen Compression (IVF)- “The pinched nerve.”

Comparing a pinched nerves pressure to that of a garden hose.
You ever pinched a garden hose so you could super soak your brother or sister from a greater distance? This creates a space advantage to run away before getting clabbered?

Well:
That occurs because you effectively increased the pressure, but the overall volume of water is actually dramatically decreased. This is the same thing that occurs with blood flood (that supply the nerve) at this IVF opening for the nerves.

Don’t believe me?
Try filling up a bucket with a pinched hose vs unrestricted hose and see which on fills up faster.

That’s a simple way to explain what’s occurring at this IVF.
There is a essentially a hole in the bone that the nerves of the low back exit to start their decent down the back of the leg.

A pinched L5 nerve in low back from a disc herniation.his whole can create a compression “pinched nerve” and give you sciatica and walking problems.This hole is the most common location of compression (pinched nerves) and irritation of nerves of the lower back.Common reasons of pinched nerves at the IVF:

Any decrease in the size of this hole can create low back pain and sciatica.

  • Herniated Disc, Slipped disc, bulging disc
  • Arthritis- Bone deformation decrease the overall size of the IVF.
  • Inflammation
  • Fluid dynamics- “Blood flow congestion aka Pinched hose analogy”
  • Poorly controlled movement that stress the nerve

Scientific studies have showed us that this hole in the spine increases and decreases it’s dimensions with various movement patters. So we know that certain movements increase the size and others decrease it. So repetitious movement in a closing direction (smaller hole) is a logical mechanism of pain generation for sciatica.

2) Excessive Sitting

Sitting is known to cause many painful areas of the body including low back pain and sciatica.

One of most common complaints of patients with sciatica is that leg pain is worse with long periods of sitting. This pain could be as soon as a person is seated with severe cases. Minor cases can take a few hours to creep up.
Scientific studies have showed us that this hole in the spine increases and decreases it’s dimensions with various movement patters. Sitting is theorized put strain on the sciatic nerve.
Experiencing sciatica while sitting is generally due to strain on the low back. Thus creating referral down the back of the leg into the sciatic nerve.
Remember that hole?

3) Improper lifting Mechanics

The majority of cases of sciatica and leg pain are referral from the low back. Therefore lifting mechanics becomes a vital aspect of both creating and eliminating sciatic nerve pain.

“The common myth is that you “should lift with your knees”. In reality you should be lifting with your hips.” Quotable
Lifting with your back, rather than with your hips place forces on the spine that overtime can create sciatica. World leading expert in spinal biomechanics (Stuart McGill) shows that lifting with a forward flexed position can injure the lumbar disc after many repetitions. This is common know as a herniated disc.
This herniated disc created then can decrease space in the IVF mentioned in #1 and create sciatica regardless if the low back hurts at the time.
This generally occurs when there isn’t enough core stability or the weight that’s being managed isn’t directly under the plum line of the person.

4) Poor Control of the Pelvis

Walking and running requires that a person is able to control the pelvis. Therefore managing impact forces of the foot interacting with the ground is crucial!

The Egg Drop Analogy.
If you throw an egg up in the air and catch it with a stiff hand?
What Happens?
It Breaks…
If you throw an egg up into the air and disperse the energy over a larger range of motion (as you catch it), then it doesn’t break.
Crazy I know…
This is the way I explain the importance of being able to control yourself, before you wreck yourself.

The picture on left is showing pelvic drop that can occurs during walking and running.
This occurs due to a poorly controlled pelvis.
Remember that hole in the spine where nerves can become pinched.?

Well:
When the pelvis drop occurs there is an increase in strain on the joints and nerves of the low back. Similar to stepping off a curb when you didn’t expect it. It Hurts!
This is one of the most common reasons that I see for sciatica in runners.
This runner was complaining about sciatica after running.

5) Deep Fascia and Muscle Tightness

Example of how the deep fascia is important for normal glide and slide of the muscles.

Have you ever wore a tight pair of pants that limited your ability to move?
What happens?
You lift your leg, the pants bunch up and then you have to move from the spine to accomplish the task.
This is similar to what occurs when your muscles and fascia are tight.
Group of muscles are covered by connective tissue that encases the muscle group much like putting sock on a your foot.
That sock decreases friction and allows you to slide on your shoe with more ease. Especially if you have those fancy dress socks on.

Well:
Fascia surrounds muscles decrease friction of muscle groups allowing proper gliding and sliding next to each other. This is pivotal to ensure normal biomechanics. When gliding and sliding are altered in the low back or hips it can put increased pressure on the sciatic nerve. Therefore creating that nagging sciatica that can occur with walking and standing.

6) Decreased Flexibility of the Sciatic Nerve.

Myth Buster #1:
It’s common belief with both patients and some doctors that nerves don’t stretch.
Wrong:
Nerves are made of highly elastic (stretchy) connective tissue and need to be able to stretch during normal human movement with walking, running and even doing the splits. (ouch for me)

Research has found that nerves can stretch up to 22% before failure. That’s increasing their length by 1/5!
If the sciatic nerve becomes tight, then it can become sensitive, creating sciatic nerve symptoms.
So all you need to do is stretch your hamstrings….. right?

WRONG!
The sciatic nerve and the hamstrings need to be stretched in 2 completely different

“Stretching your hamstrings will make sciatica worse, not better”

Part 2: How Do I Treat my Sciatica at Home?
I know it must be killing you by now.
So…
How do I Stretch the Sciatic Nerve?
We need to understand some fundamentals about nerves personalities (neurodynamics) in order to understand how stretch them. I’ll keep this Joe Dirt Simple. Nerves hate sustained tension (stretch), compression and being deprived of oxygen.
They love being in a position of rest, being slacked and receiving lots of oxygen.

My “go to favorite” home remedies for sciatica is the Standing Leg Swing Nerve Stretch
Step by Step Instructions

  1. Hold on to something!
  2. Kick the painful leg forward until you feel a very light STRETCH in hamstring, back or even calf. There should be NO PAIN. If this is a very short distance than that’s completely OK!
  3. Do 15 repetitions.
  4. Take a full 60 seconds break.
  5. Do this 3-5 times a day if the pain isn’t made worse. If so, consult a medical professional. (recommended regardless)

This is a safe way to stretch the sciatic nerve by giving it what it loves, rather than what it hates.

Take micro breaks as a method to relief low back pain and sciatica. (Then eat a Kit Kat as a reward;)

Ok,
So what’s Next?

Sitting is the New Smoking: Take micro breaks to Relief Sciatica and Low Back Pain.
Back in the 90’s it was popular in the corporate wellness world to have professionals come and give long ergonomic advice workshops.
Unfortunately the only ergonomic position that can relieve your low back pain and sciatica is the position that you frequently take a break from.

The 45:1 rule
Stand up and move for one minute every 45 minutes you’ve seated.

Creating a New Habit- Hip Hinging
Since the majority of sciatica is referral from the low back we need to move in such a way that doesn’t put unnecessary stress on the low back.

To put this simple- move from you hips rather than the spine.

The Kiss the Wall with your Butt Exercise

  1. Stand with feet just a few inches from the wall.
  2. Then bend forwards with your body so that only your butt touches the wall.
  3. Move your feet a few inches forward
  4. Continue this until you are far enough away from the wall that you could sit into a chair.

Standing Like a Boss- How to Stand Without Sciatica
Sciatica and low back pain while getting out of a chair is one of the common reasons that patients seek my help. Usually this patient will press his/her hands on the knees as a point of perceived stability to push themselves into a upright position. This puts the low back in a position of strain due to most of a persons upper body weight being in front of the persons body.

Exercises to Avoid While Experiencing Sciatica

During acute sciatica there are number exercises that most likely will make the symptoms worst in the long run.Even if theses exercises makes your leg pain feel better for ten minutes, and then that nagging leg pain returns with a vengeance.
Sound Familiar?

Top Exercises to avoid when you have acute sciatica. (most cases, not all)

  • Forward fold from Yoga (See left)
    Sustained stretching of the hamstring and low back (See above)
  • Burpies

It’s important to note that these are only exercises to avoid while the sciatic nerve is actively generating pain. Once the leg pain has been addressed these exercises can be reintroduced.
