Questions this episode answers
- When is lower back pain an emergency?
- Go to the ER if you have numbness in a saddle shape on your butt, foot drop where your toes slap the ground as you walk, or you can't fully empty your bladder. Any one of those can mean emergency surgery. Without them, it's usually a rehab case.
- Why does bending forward hurt my lower back?
- When bending forward is the trigger, a lot of times it's a disc injury. I think of it like a scab that gets ripped off every time you flex, so we limit flexion while it heals.
- What exercises help a disc injury that hates bending forward?
- We normally start with positions that don't hurt, like supermans, bridges, single leg bridges and McKenzie extension exercises. I avoid sit-ups and crunches, and I may limit squat depth so the low back doesn't cave.
- What is the difference between a disc injury and facet syndrome?
- They're opposites. A disc injury usually tolerates extension and hates flexion, while facet syndrome tolerates flexion and hates extension. Facet syndrome is usually easier to deal with.
- Should a disc injury be adjusted by a chiropractor?
- I personally choose not to adjust a disc injury, because an adjustment involves some flexion and rotation. For extension-related pain I would, unless there's a chance of a pars fracture.
- Why is my lower back worse in the morning?
- After a night lying down, the disc holds more fluid, and bending forward first thing doesn't agree with it. If you're flexion intolerant, try McKenzie extensions in the morning instead of folding forward.
Start with where the pain goes
The first thing I need to know is simple. Is your pain going down a leg, into the thigh, the knee or the foot? Or is it staying in your back?
If it travels, we work to centralize it first. Centralization means getting the symptoms to move back toward the center of the spine, toward the back and hip, and especially away from below the knee.
This matters because surgical decisions often revolve around referred pain like that. How far it goes down a limb counts. So does whether it goes down both.
Three red flags that mean the ER today
Whether it's a disc injury, facet syndrome or a tight low back, I screen for three things. If you have none of them, there's time. It still hurts, and I get that. But it's usually a rehab case.
If you have one of these, go to the ER. It's possibly emergency surgery.
- Saddle anesthesia. Numbness or loss of feeling in the shape of a saddle on your butt, on both sides.
- Foot drop. Your toes can't stay lifted, so your foot slaps the ground with every step down the hallway.
- Urinary retention. You try to empty your bladder and can't get it all out.
If your doctor hasn't asked you about these, figure them out.
Flexion or extension: which hurts less?
Next question. Does it hurt more bending forward (flexion, like touching your toes) or arching back (extension, like a sea lion on a postcard with its head and tail in the air)?
I'll say it again. Are you more tolerant to flexion or extension? It's not about which one is pain free. It's which one is less painful.
If bending forward sets off your back, a lot of times it's a disc injury. Facet syndrome is the opposite. It tolerates flexion and hates extension.
This drives the whole program. Your back has stabilizers, like the multifidus, that should fire before you bend, turn or pick up a pencil. With disc injuries they often fire late. They stop doing their job. Train them in a painful position and they shut down again.
So we put you in positions that don't hurt, then wake those muscles up. For someone who can't bend to tie their shoes, that might be supermans, bridges, single leg bridges, or McKenzie extension exercises to help centralize the pain. No sit-ups. No crunches. Maybe no deep squats, where the low back caves into a "butt wink."
With facet syndrome, crunches, squats and front squats become safer options. It's not a great condition to have. But it's usually easier to deal with than a disc injury.
Stop picking the scab
Think of a disc injury like a scab. Every time you flex forward, you rip it off. Every time, you reset the clock a little.
I hear it constantly. "When can I go snowboarding?" Fair. But are you flexing forward in your car? If you can't drive more than five minutes, the answer is yes.
Pick a scab and it takes longer and longer to heal. Visualize that. Limit flexion.
On adjustments: I personally choose not to adjust a disc injury, because an adjustment has some flexion and rotation in it. Other doctors may see it differently. For extension pain, I would adjust, unless there's a chance of a pars fracture. That's a different situation.
And those tight back muscles? When an area isn't strong enough to protect itself, the muscles around it fire up to stabilize it. The tightness is often a response, not the root cause.
Move your hips so your back moves less
If your hips move well, your low back moves less.
Picture picking up a baby. Arthritic, stiff hips mean you bend with your back. Good hips and strong legs mean you squat or deadlift down.
You squat all day. Into your car. Into your work chair. On the toilet. Get good at it and limit flexion while you do.
People argue with me about deadlifts. You don't need to pull 150 pounds. But I think you should be able to deadlift at least 65. Kids, heavy backpacks, a table, helping a friend move. All deadlifts.
The goal for your trunk is rigid. By rigid I mean robust. By robust I mean resistant to big movement away from midline. It can sway a little, just not a lot. One client finally got it after weeks of hip hinging: "You don't want me to move my trunk." Exactly.
If flexion is your problem, try McKenzie extensions in the morning. After a night lying down, the disc is fuller of fluid. Bending forward first thing doesn't agree with it. Extend instead. There's no reason to flare it up before breakfast.
Key takeaways
- If pain travels down your leg, the first goal is centralizing it back toward your spine.
- Saddle numbness, foot drop or trouble emptying your bladder means the ER today.
- Find out whether bending forward or arching back hurts less, and train in the direction that hurts less.
- With a disc injury, every forward bend is a picked scab that resets your healing clock.
- Better hip movement and solid squat and deadlift patterns mean less low back movement in daily life.
- A robust trunk resists big swings from midline; it doesn't have to be frozen.

Welcome to the Performance Place Sports Care Podcast, where you can learn about sports injury theory, rehab, diagnosis, and how to understand the doctor lingo you didn't understand at your appointment. And now, your host, Dr. Sebastian Gonzales. Hey, it's Dr. Sebastian Gonzales with the Performance Place. And this time, we're going over back injuries. And back injuries, we're talking about disc injuries, facet syndrome, generalized low back pain, muscle tightness around the back or low back. And the reason why I'm bringing this up today is because I have this conversation a lot with patients at the office. And I want to make sure that I know it's a little bit high pressure, especially in the beginning when you have an injury.
It's very stressful to absorb all the information that I'm saying and that is being put out at you. So, this podcast is just a nicer, gentler way of going through and just reabsorbing that content. Because understanding an injury, and especially a back injury, is super critical in regards to changing your activities of daily living so you have a chance to heal up as well. And activities of daily living are very simple things. And they're activities like putting on your shoes, getting out of bed, washing dishes. All these things are things that a lot of patients that I've worked with do not think of at all as being triggers for their back condition.
Now, in case you're wondering the rough algorithm that I'm going through at the office when you come in and you start speaking about a back injury, First off, we just have to figure out whether it's going down a leg into the foot, into the knee, into the thigh, or not. Because if it is, we need to make sure that we centralize it first. And centralization is the concept that you can look up on Google. And centralization is mainly that we're trying to get that pain or the symptoms to become more centralized, to become more towards the center of the spine, towards the back, towards the hip, and especially away from being further distal or downward from the knee.
So that is the first number one thing. And the reason for that is because a lot of times surgical procedures are more so revolved around a referred pain like that, or how far it goes down into a limb, and especially if it goes down into both limbs and so on. One question I ask as well, when someone comes in with a possible disc injury, by the way, we're talking about not just disc, but also Pisset syndromes, or also muscle tightness to the low back, is we need to figure out if this is a back injury that has one of these three situations, then it's a medical emergency. All the other conditions that don't have these, there's time to wait.
And I'm not saying that it doesn't hurt, and we don't understand that it hurts, that it's very uncomfortable to you, and that's, I understand. But a lot of times there are rehab cases if they don't have these three things, and here's the three. Number one is saddle anesthesia. And this is numbness or loss of sensation in the shape of a saddle on your butt. And keep in mind that encompasses both sides, not just one. Second thing is what we call foot drop. Foot drop is, imagine, you know, someone walking down a hallway, and you can hear them coming because you hear this slap. And the slap is that the foot is, or the toes of the feet cannot stay elevated, and they're just slapping the ground every time that person is walking down the hallway.
So drop foot is definitely something you need to go see, be seen in the ER for. Last is urinary retention. And urinary retention is where you're trying to go to the bathroom and get it all out, but you can't. So if your doc hasn't asked you about these, you really need to figure them out. And if you have one of these, this is an ER visit, and it's possible emergency surgery. Now, the next thing that I ask people is, does it hurt in one of two directions? And then we can figure out the rest from there. And the two directions, if you haven't listened to the Common Terms podcast yet, are flexion or extension.
I'll explain both of them. Extension, most people can understand because when you extend your elbow, it's going backwards. And this happens the same way with the back. If you were to look back over your head, so you're standing, you're looking back up into the sky, that's neck extension. But also times, a lot of times, the low back will extend as well. So, extension is almost, I guess, like if you imagine, I remember one of those seal postcards or sea lion postcards, where they're on their belly and they're extended up and they're looking to the sky and their tails in the sky as well. This is hyperextension, overextension.
So that's one motion, extension. Flexion is the other direction. It's like you're bending forward to do a forward fold in yoga, or you're bending over to touch your toes. And this doesn't always require the lumbar spine or the low back to move, but oftentimes it does. And when it does, if this sets off or becomes a trigger for your low back condition, a lot of times it is a disc injury. And disc injuries can go to varying degrees. So let's not go into that too much. But for the most part, when we're establishing rehab with a back injury, we need to figure out one thing in regards to program design.
And that is, are you more tolerant to flexion or extension? Okay, I'm going to say that again. Are you more tolerant to flexion or extension? And it's not about if one of them is pain free or not. It's which one is less painful. Okay. And the reason why we're doing this is because the muscles of the back need to be rehabbed. And these stabilizer groups, one of them that they've done a lot of research on in the past is called the multifidus. They're supposed to be stabilizers at the low back and protect the region prior to movements, such as prior to bending down, turning and picking up a pencil.
But a lot of times with injuries such as disc injuries, these muscles become really latent and they fire late. So they're not doing their job. And a lot of times we're just tearing up the back if we don't stabilize and retrain these muscle groups. So the only problem is if we train them while you're in pain or put you into a painful motion such as flexion, in this case, if the disc injury doesn't like flexion, then these muscles are shutting down again. So how are we actually getting them to fire up and do their job? The answer is, is we put you into positions which don't hurt and then we stimulate those muscle groups.
So an example of some exercises which I give people with that are flexion intolerant, such as they can't bend down to tie their shoes, is supermans. Or we might give them bridges, single leg bridges. We might give them McKinsey extension exercises, which more is a means to centralize the disc and create some referred, get some referred pain to go away from the lower limbs. But things we definitely wouldn't do with them are sit-ups or crunches. We probably, we might not have them squat beyond a certain depth because a lot of times the low back will cave and create a slang term called butt winking.
And we do have a video on this as well. Look at our squat video. So there's certain things that we won't have you do, but I want you to realize that some of the methods or some of the movements we're teaching in the office here, they are helpful in regards to limiting flexion of the spine by getting the hips to move better. And I'm going to say that again because there was a patient this week that we talked about this about the second or third time now. And I really, really need you to understand this is that if your hips move well, your low back moves less. Let's think about it in a real life setting.
If you have to bend down to pick up a baby and your hips are arthritic and not working, then you're going to bend over with your back. If your hips work well and your legs are strong, you're probably going to squat down or deadlift down and pick up this baby. Now, the complex lift that we show in the office that are needed through everyday life, everybody needs to learn how to do them well, maybe not with a ton of weight, but they need to learn how to do them well, are deadlifting and squatting. Here's my examples. Okay, squatting. How many times do you squat a day? Well, you're squatting to get into your car.
You squat to get down to a seat while you're working. If you do work in a chair, you're squatting to go to the bathroom. All of these are squatting motions that we might as well get really good at and limit the amount of flexion that you have while doing it. Because I can tell you, I have patients that they cannot tie their shoes in the morning because they're getting flexion of the lumbar spine. And so part of our job here is to teach you guys how to limit flexion while you're doing some of these daily activities. Now, deadlifting is one that people argue with me to the blue in the face sometimes about.
They're like, why do we have to do this? Why would I have to deadlift 150 pounds? Well, you don't. But you should probably be able to deadlift at least 65. So, picking up a child, picking up, let's see, a heavy backpack, a log, a table, helping a friend move. These are all motions that require deadlifting. And if you learn how to keep the spine or trunk stable with this, then you should be really good. Now, I had a patient also over the last couple of weeks that he had an epiphany. And it was probably about a fifth or sixth time. And we were doing some deadlifting or hip-binging motions. And he's like, I got it.
And I was like, you got what? And he said, I realize now you don't want me to move my trunk. I said, okay, yeah, yeah. We've been talking about this for a while. He's like, I know, but I finally got it. And again, this is part of the reason for these podcasts is I want you guys to, I want to hammer in what we really, really need you to know. And the goal of the trunk in these rehab settings are to keep it as rigid as possible. And by rigid, I mean robust. And by robust, I mean resistant to deviation from midline. If I were to come up and you were sitting in a chair and you had a disc injury and I pushed you forward and you flexed forward, you wouldn't be happy with me because it probably really hurt.
But if you were ready for that and engaged in the trunk and it came up and you didn't deviate much from midline, your trunk is robust. Robustness is a very, very important thing in regards to stabilization. It doesn't mean that it can't move or it's resistant to movement. It's just resistant to a large amplitude of movement. It doesn't sway a lot. It sways a little bit, but not a lot. And that's how we protect the spine. Now, an analogy which I've gone through in a lot of people with disc injuries, I know we've been talking about disc injuries, not as much with Passett syndromes or things that are extension tolerant.
We will talk about that in a second. So, disc injuries, think of them like a scab. And I cannot stress this enough. Once you get it into your mind that there is a scab on the spine which gets ripped off every time you flex forward, you will stop doing it. And I tell patients over and over again that as soon as you flex forward, you've reset your clock a little bit. Well, when is this going to get better, Doc? I have a snowboarding event I really want to go to. I'm going to go ride this year and so on. I know. I get it. But when you're driving in your car, are you flexing forward? Well, yeah, I am.
I can't drive any more than five minutes. Okay. Look, let's not reset this clock. Understand that when you pick out a scab, it takes longer and longer to heal. So, visualize that. Do not pick the scab off. Limit flexion. Your injury does not tolerate flexion. And if you need to know more about what flexion is, there is a Common Terms podcast. On the intro course that you really, really should listen to. Because we go over a lot more than just flexion. We go over all the motions as well as some of the joint and muscles and so on. Now, with extension tolerant conditions such as facet syndrome, these are ones that I think would be more responsive towards adjustments.
And I know some of you have come in and talked to me about, well, should we be adjusting this disc injury? I personally choose not to. Mainly because there's some flexion and rotation within an adjustment. I'm not saying it doesn't work for other doctors. It's just something that I would not rather dabble with. Now, extension pain, I would. Unless there's a possibility that you have a parse fracture, which is a whole different situation. Now, with extension tolerant, or sorry, sorry, I erased all that. With flexion tolerant, so facet syndrome will be responsive and tolerant towards flexion. So, it will be the direct opposite of a disc injury.
So, you won't be able to extend. So, now we can have you do more things like crunches, squatting, front squatting, and so on. And it's a little bit safer. And facet syndromes are not, by all means, they're not great conditions to have. But they're not as hard to deal with as disc injuries. So, now there are many other conditions at the back. And I know the muscles get tight and so on. But remember this, if you have an area of instability or it's not strong enough to protect itself, and this could be one vertebra upon another, it could be a disc which is injured, it could be a lot of things, a lot of times the muscles will fire up because they are doing what they can to stabilize that area.
And this happens a lot. It happens with shoulder labrums. It happens with a lot of conditions. So, I hope this was really helpful. There will be some videos on exercises you guys can do that we show very commonly in the office. One is the McKinsey Extension Protocol, which is something you might consider doing in the morning, especially if you have a disc injury, not a facet syndrome. If you are flexion intolerant, if you cannot flex, the McKinsey Extension Protocol is usually a great one to start with in the morning because in the morning, the disc is usually more full of fluid because you've been horizontal to gravity the whole night.
So, it fills up a little bit more. And in the morning, as soon as you get out of bed and you start stretching a little bit and go into flexion, it doesn't like it. So, go into extension and give it a chance. Give it a chance to feel good throughout the day. There's no reason to flare it up first thing in the morning. Now, if you guys have other secondary level questions, I really, really invite you to put them down below this podcast. I want to answer the more in-depth questions when they come up because if you're thinking of them, someone else is too. Talk to you guys soon.
