Sciatica vs Slipped Disc: Video Explanation

Sciatica vs slipped disc compares two different kinds of term. A slipped disc describes a structure: disc material pushing beyond its outer wall. Sciatica describes a symptom: pain traveling along the path of the sciatic nerve. A slipped disc is a common cause of sciatica.

That distinction changes what gets examined. In this video, Yama Zafer, D.C., explains how the two relate, why some disc involvement has been present in every case of sciatica he has seen, and why the examination settles more than the report does.

Sciatica vs Slipped Disc: Key Takeaways

PointWhat to know

What the video covers

Why sciatica describes a symptom rather than a diagnosis, how the sciatic nerve forms and runs, how disc problems involve the muscles and fascia, daily habits, the psoas, and why forceful cracking and early surgery are avoided.

Sciatica is a symptom

Sciatica describes an irritated sciatic nerve, with pain down one leg that can turn into numbness, tingling and weakness; it can affect both legs, with one side usually worse.

The disc connection

A slipped disc is one common cause of sciatica, and Yama Zafer, D.C., explains that some disc involvement has been present in every case he has seen, which is why the spine is examined and not only the leg.

Muscles and fascia

The muscles and fascia of the back, buttock and leg share nerve supply with the sciatic nerve, so an irritated nerve can leave them tense, with trigger points that also need attention.

Daily habits

Breaks from sitting and walking keep the spinal joints moving, and side sleeping is suggested; exercise and stretching have to be condition specific and age appropriate.

The psoas

Stretching the psoas, a major hip flexor attached to the lower spine, may suit some people but not anyone who is not ready for it or who has spondylolisthesis, where a vertebra has slipped.

What is avoided

Forceful cracking, twisting and yanking are avoided on a spine with a damaged disc, and surgery is the last option, after condition-based conservative care has been tried.

Video Summary

This sciatica vs slipped disc video explains how sciatic nerve symptoms relate to spinal disc changes and why symptoms may travel into the leg. It clarifies that sciatica describes a nerve-related pattern rather than a specific diagnosis and often connects to changes in the lower spine.

The video also explains how disc-related irritation can influence surrounding muscles and fascia, how posture and daily habits affect spinal loading, and why identifying the source of symptoms is important when considering movement and activity choices.

Arranging an Assessment for Sciatica or a Slipped Disc

To arrange an assessment for sciatica or a suspected slipped disc, see the Bukit Damansara contact page and the Bandar Sri Damansara contact page, or call either center directly:

The first visit begins with a history and an examination of the lower back, the hips and the nerves of the legs, including how far the symptoms travel and whether an MRI is needed, before any care is discussed.

Find both centers on Google Maps: Bukit Damansara (KL, main center) and Bandar Sri Damansara.

Sciatica vs Slipped Disc Video: Chapter Summaries and Edited Transcript

Each chapter below opens to a short summary and the edited transcript of that part of the video, with its start time. The video is also on YouTube, alongside the rest of the Chiropractic Specialty Center channel.

Sciatica Explained: Symptom vs Diagnosis (00:00)

Summary: Yama Zafer, D.C., explains why he calls sciatica a loose term rather than a diagnosis: it describes an irritated, inflamed sciatic nerve, the longest nerve in the body, without explaining what is causing it.

Edited transcript: Sciatica is a cop-out diagnosis! It's just telling you your sciatic nerve is not happy. To me, the purpose of a diagnosis is to explain what is happening with that patient. Sciatica is a loose term. It's not a diagnosis to me! It's descriptive of a symptom. It means the sciatic nerve is inflamed. The sciatic nerve is the longest nerve in the body.

Summary: The sciatic nerve forms from the fourth and fifth lumbar nerves and the first and second sacral nerves, with some anatomical variation between people. He explains that sciatica is a nerve issue rather than a muscle issue, and that the compression behind it often comes from a slipped disc in the spine.

Edited transcript: It originates from this nerve, the fourth lumbar nerve, the fifth lumbar nerve, the first and second sacral. In some people, there are variations... Some anatomical differences exist... goes back here under the buttock, down the leg. Sciatica is not a muscle issue. It's a nerve issue. And that issue often and always comes from a compression that exists oftentimes in the spine, resulting from a slipped disc.

Summary: Sciatica usually affects one leg but can affect both, with one side usually worse. Pain can turn into numbness and tingling and, over time, weakness, because the fibers that form the sciatic nerve are being compressed.

Edited transcript: Symptoms: pain down one leg. Usually sciatica by definition is on one side, but it can happen both sides. But they don't say, oh, that's not sciatica. Well, it is sciatica bilaterally. That's happened before, but one side will predominantly be more painful than the other. Then it turns into numbness and tingling, and eventually becomes weak. Sciatica is due to compression of the fibers that form the sciatic nerve.

Summary: He shows where the nerve fibers join into one bundle under the buttock, run down directly behind the hamstring and then branch out down the leg, and repeats that the word sciatica only says the nerve is irritated, not why.

Edited transcript: The sciatic nerve gets its name as a sciatic nerve at this point in my buttocks, because fibers from here, two fibers from here, they come together, form one bundle, go down through here under my buttocks, and at that point where they form one bundle is then referred to as the sciatic nerve, and it goes down behind my hamstring, right directly behind my hamstring, right about here. Then it branches out into multiple fibers going all the way down. But the important thing to realize is that sciatica to me, as I said, is a cop-out diagnosis, because it's just telling you your sciatic nerve is not happy. To me, the purpose of a diagnosis is to tell you exactly what's happening with that patient. Sciatica is too loose.

Summary: In his experience, some disc involvement, from mild to moderate, has been present in every case of sciatica he has seen, and a disc problem does not stay limited to the disc.

Edited transcript: I happen to believe everyone with sciatica will have a spinal disc issue. I have not seen a condition where there's a sciatic nerve or sciatica-like symptom and there's no disc damage. In every case that I have seen, there is some disc involvement, but the degree will differ; it could be from mild to moderate. The most important thing that you have to realize for sciatica is that when, as I said, that is from a disc, it's not gonna be just involving your disc.

Summary: The muscles and fascia of the back, buttock and leg share nerve supply with the sciatic nerve, so they become irritated too. Irritated muscles tense and spasm, trigger points develop and the fascia loses its elasticity, which is why the muscles and fascia are checked as well as the disc.

Edited transcript: It can also trigger muscle reaction. Our muscles are covered with fascia: the muscle and the fascia that it's covered with, especially in the back, in the buttocks, down the back or side of the leg. These all get their neuronal stimulation, their nerve supply, from the lower back, from the same fibers where the sciatic nerve comes from. So if the nerves in here are irritated, these muscles, including the ones on your bum, the hamstring, the IT band, the calf muscles, they all get irritated too. When a muscle is irritated, it can contract, it can be spasmodic, it can stay tense, and over time, that becomes a problem in itself. You develop trigger points, and that will make this worse, and this will make those worse. And if that goes on, then you'll have myofascial pain. The fascia that covers the muscle also gets damaged. Everything is supposed to be elastic. The elasticity is gone, so the stretchability is gone. The tissue covering the muscles, the damage, the muscles inside is damaged. Those two damages combined are gonna make your sciatica worse. And when it comes time to get treatments, you gotta address all of those issues, which is why a lot of times I say, is it painful here? Is it painful here? I look for those trigger points or myofascial points, because addressing only this part and not here is not helpful for you, and you have to be careful not to do things that would make it worse.

Summary: He reminds viewers to keep good posture, take breaks from sitting and walk, because pressure builds with prolonged sitting and every step moves the joints of the spine. Side sleeping is suggested.

Edited transcript: The do's and don'ts. A reminder for you all: maintain good posture. Take breaks. When you're sitting for a prolonged time with no movement, pressure builds and builds and builds. Just getting up and walking around mobilizes things. And when you get up, put your hands here and feel how much movement there is, right in your spinal column, right next to your fingers! You'll notice it does one of these things when you walk. Every single joint in your body, the joints between your toes, the joints between your spinal segments, with every step they mobilize. And it's good for them. It depressurizes them. Mobility is good. So take breaks, sleep on your side.

Summary: Exercise and stretching have to be condition specific and age appropriate, and start only when the person is ready, because disc and nerve problems bring muscle and fascia problems with them.

Edited transcript: Now, what to do? Exercising and stretching, in order to be beneficial, has to be condition specific and age appropriate. Two of the things that most patients miss. Muscles are important. Not that it's not as important as, let's say, your disc. Your disc is most important because it protects the nerve canal, CSF flow, everything else. But if you have disc problems, if you have a nerve impingement, you will develop muscular issues. You will develop problems with your fascia. So a good stretch to do, you have to break that. Only when you're ready. If you're not ready and you do these exercises, you create more problems. But there have to be fascia exercises. There has to be stretching of muscles.

Summary: He introduces the psoas, a major hip flexor attached to the lower spine and the hip, and explains that a tense psoas can tilt the pelvis and affect sciatica, because muscles work in opposing pairs.

Edited transcript: This one, I'm pointing here. This is for the psoas. It is a major hip flexor. It attaches under your belly, to the spinal segments here, and down to the hip. Big muscle, two of them, major and minor. You need to stretch it. Aside from it, there are psoas release techniques. I did it for you earlier. Okay... Because when you release this, yes, it's not part of the sciatic nerve, but the entire body is connected. It's part of your pelvis. When this is tense, you'll have a tilt that will impact sciatica. What happens here is not isolated. This impacts this. This impacts this. Yin and yang: muscles have agonist and antagonist. For every movement, there's an opposite muscle that does the opposite. Psoas is this, so you have to stretch it.

Summary: He demonstrates a psoas stretch on a small stool and explains that it is not for anyone who is not ready for it or who has spondylolisthesis, and that people should check with their own doctor or chiropractor first. The stretches continue after symptoms improve, because recurring problems are common, with only light hamstring stretching, since pulling hard on the leg can flare the sciatic nerve.

Edited transcript: The best way to stretch it is to... I sat on a small little stepping stool and I pushed and leaned back. If you're not ready for this and you do this, you'll have a lot of pain. And if you have a spondylolisthesis, a situation where the bone also slips in addition to the disc, you have no business doing that. So when I recommend these exercises, it's not for everyone. Make sure, if you're my patient, we talk, we tell you. If you're not one of my patients, you talk to your doctor and you make sure it's specific for you before you just... “Oh, he talked about it in a talk.” Not just because I talk about it. It doesn't mean it's right for you. These are good exercises, only if it's appropriate for you. So yes, while this is good for certain instances, it's bad for others. If you have a stable sciatic and a stable disc, in other words, you're stabilizing, and now you wanna make sure you don't go through the same thing, because recurrent neck and back issues are common. Over and over and over. They get better. They say, well, it's coming back. I thought I was over it. No. As soon as you get improved, you get over it? That's not when you... okay, I'm going home. No, the game is not over. That's when you start these things, to make sure it doesn't come back again. Okay, this is a good psoas stretch. Quadriceps stretch. You hold this one; you kind of lean back a little bit to get the psoas going. This one is mainly for the front of the thigh, so, as you can see there, I did this, and then you push back until you feel the burning, the stretching, but not “oh ho oh,” that level. A little bit of hamstring. Nothing too aggressive. A lot of times people say, oh, lie down, pull your leg. God, that's gonna be too excessive. The sciatic nerve that goes on down the back: you pull it down like that, it's gonna stretch. It's gonna become flared.

Summary: Whether the problem is sciatica, a disc bulge or a disc herniation, he advises against cracking, twisting and yanking on a spine with a damaged disc, even by an experienced chiropractor, and explains that he uses rotary manipulation only when he is sure there is no disc damage.

Edited transcript: Whether you have sciatica, disc bulge, disc herniation, some people will say, I'm gonna crack your back. Others will say, I'm gonna grab your neck and yank really hard while my buddy pulls on your ankles. And some will say, no, you need a little bit of steroid injections. Others will say you need a little surgery. I wouldn't recommend any of those. The cracking and twisting, even if it's done by a very well experienced chiropractor, should not be done on a spine that has a damaged disc, because it will tear that spine apart. I am not a big fan of rotary chiropractic manipulation. I only do it when I am 100% sure that there's no spinal disc damage. Because how can you be sure? So it's better to be safe than sorry.

Summary: Invasive procedures have their place, and when his care cannot help he sends the person to a surgeon, but for disc problems surgery should be the last option, after the conservative route has been exhausted.

Edited transcript: So some people have surgeries prematurely. I would recommend: do not do invasive procedures. Not that they shouldn't be done. Yes, they have their place. There are times I cannot help. Sorry, too late for me. You go talk to the surgeon, but... if you have spinal disc issues, even if it's a herniation or bulge, surgery should be the last option. Exhaust conservative route.

Summary: Conservative care has to be condition based and must not harm, which rules out cracking, Thai massage or having someone walk on the back. What a person does with posture and habits in the other 22 hours of the day is part of the care.

Edited transcript: Now, conservative route does not mean you go crack your neck and back, get someone to do Thai massage on you or get your kid to walk on your back. It has to be condition-based and appropriate conservative care, ones that don't harm. Okay? And then on top of that, conservative care is not just that; in a day, there's 24 hours. I see a patient 30 minutes, two hours. What about the other 22 hours? You have to mind your posture, your habits, you change. So start making these changes now.

Key Considerations for Sciatica and Disc Health

  1. Maintain neutral posture during sitting and standing
  2. Take regular breaks to reduce prolonged pressure
  3. Avoid excessive bending or twisting movements
  4. Ensure exercises are appropriate for your condition
  5. Review daily habits that influence spinal loading
  6. Avoid forceful twisting or aggressive movements when disc-related or nerve-related symptoms are present
  7. Do not take up yoga: when a slipped disc lies behind the sciatica, yoga must be avoided

Whether leg pain comes from sciatica or a slipped disc, get urgent medical attention, a thorough assessment by a competent clinician the same day, if you develop new or worsening numbness around your genitals, between your genitals and anus, or around your anus. New difficulty passing urine, or any loss of bladder or bowel control, needs the same urgent assessment. These symptoms can have different causes. Some may call for an invasive procedure, but an assessment helps determine the appropriate care and does not mean you necessarily need surgery. Progressive leg weakness should not be ignored and should be assessed promptly by a competent provider; conservative care may still be a reasonable route once that assessment is done.

FAQs About Sciatica & Slipped Disc (Video)

These questions highlight key concepts related to sciatica and spinal disc changes explained in the video.

Is sciatica a diagnosis or a symptom?

In the video, Yama Zafer, D.C., calls sciatica a loose term rather than a diagnosis. It describes an irritated sciatic nerve, usually felt as pain down one leg that can progress to numbness, tingling and weakness. A diagnosis has to explain what is irritating the nerve, which is why the source in the spine is examined.

How does a slipped disc relate to sciatica?

A slipped disc is one common cause of sciatica: disc material pressing on the nerve roots in the lower back can irritate the fibers that form the sciatic nerve. In the video, Yama Zafer, D.C., explains that some disc involvement, mild to moderate, has been present in every case of sciatica he has seen.

Where does the sciatic nerve run?

Nerve roots from the lower back and the sacrum join into one bundle, the sciatic nerve, which passes under the buttock, runs down behind the hamstring and then branches into smaller nerves toward the foot. That path explains why sciatica can be felt in the buttock, the back of the thigh, the calf or the foot.

Why do the muscles tighten with sciatica?

The muscles and fascia of the back, buttock and leg get their nerve supply from the same roots that form the sciatic nerve. When those roots are irritated, the muscles can tense and spasm and develop trigger points, and the fascia loses its elasticity, so the muscles are examined as well as the disc and the nerve.

What daily habits does the video suggest for sciatica?

Keep good posture, take breaks from long sitting, and get up and walk, because walking moves the joints of the spine. Sleeping on the side is suggested. Any exercise or stretch has to be condition specific and age appropriate, and it starts only when the body is ready for it, otherwise it can create more problems.

Is the psoas stretch right for everyone?

No. The psoas is a major hip flexor attached to the lower spine and the hip, and a tense psoas can tilt the pelvis. The video shows a psoas stretch but says it is not for anyone who is not ready for it, or for anyone with spondylolisthesis, and people should check with their own doctor or chiropractor first.

Why are forceful cracking and twisting avoided with a damaged disc?

In the video, cracking and twisting should not be done on a spine with a damaged disc, even by an experienced chiropractor, and yanking the neck or pulling hard on the legs is also advised against. Pulling the leg hard can also flare an irritated sciatic nerve, so stretches are kept to a comfortable pull.

When is surgery considered for sciatica?

The video describes surgery as the last option for disc-related sciatica, considered after condition-based conservative care has been tried. Yama Zafer, D.C., says invasive procedures have their place, and when his care cannot help he sends the person to a surgeon, but surgery should not be done prematurely.
