You can do a full shop. Forty minutes round the aisles, no real bother. Then you reach the car park, let go of the trolley, and by the time you get to the boot your legs have gone. Heavy, aching, weak, like they belong to someone else. You sit in the driver's seat for two minutes and it settles.
Or you set off for a walk and get two hundred yards down the road before your legs or back start to protest. You stop and lean on a gate. A minute later you can go again. Another two hundred yards. Same thing.
If that sounds like your life, there is a good chance somebody has already told you it is wear and tear, it is your age, and you will have to learn to live with it.
That is not a diagnosis!
What is actually happening
Your spinal cord and nerve roots run down a bony tunnel in the middle of your spine. There is normally room to spare. Over time that space can narrow, from thickened ligaments, disc changes, or bony growth around the joints. The medical name for the narrowing is spinal stenosis.
Here is the part that explains the trolley, and almost nobody gets told it.
The size of that tunnel changes depending on what your back is doing.
When you stand up straight, and especially when you arch backwards, the canal narrows. When you lean forwards, it opens. Not by a lot, but for a nerve that is already short of room, a small change is the difference between comfortable and not.
So when you lean over a trolley, you are not resting. You are decompressing your own spine. You have found the position that gives the nerve its space back, and you can walk for as long as you hold it.
That is why people with stenosis will tell you they can walk round a supermarket all morning and not manage the length of their own street.
The classic signs
See how many of these you recognise.
Standing still is worse than sitting. Queues are miserable. Waiting at a bar or a bus stop is worse than the walk there.
You lean on things. Trolleys, prams, the kitchen worktop, the back of a chair. You may not have noticed you are doing it. Your family probably has.
Symptoms come on at a fairly predictable distance. Roughly the same point every time, not random.
Sitting down fixes it, and reasonably quickly. A couple of minutes on a bench and you are ready to go again.
Uphill is easier than downhill. This one surprises people. Walking uphill puts you in a slight forward lean, which opens the canal. Downhill straightens you up and closes it.
You can cycle further than you can walk. Same reason. You are folded forwards on a bike.
It is often both legs, though rarely equally, and it is more heaviness, weakness, cramping or a dead feeling than the sharp electric pain most people associate with a trapped nerve.
Your back itself may barely hurt. Plenty of people with stenosis have far more trouble with their legs than their back, which is exactly why it gets missed.
The distinction that actually matters
There is another condition that looks almost identical from the outside. Legs that hurt on walking, ease with rest, come on at a predictable distance. It is called vascular claudication, and it is caused by narrowed arteries rather than a narrowed spinal canal.
Telling them apart matters enormously, because they are treated by completely different people.
The tell is what relief needs.
With stenosis, stopping is not enough on its own. You need to change position. You bend forwards, sit, or lean on something. Standing still at the top of the road with a straight back will not settle it.
With a vascular cause, simply stopping is enough. Position makes no difference. You can stand upright and wait and it eases. Uphill tends to be worse rather than better, because the muscles are demanding more blood.
If your legs settle when you stop but position makes no odds, that needs a GP and a look at your circulation, not a spinal clinic. Anyone assessing you properly should be checking the pulses in your feet and asking these questions, not just booking you in.
When it is not a waiting game
Most stenosis is uncomfortable and limiting rather than dangerous. There are exceptions, and they are worth knowing.
Get seen the same day, at A&E, if you develop:
- Numbness or altered sensation around the saddle area, meaning the inner thighs, buttocks or genitals
- Any change in bladder or bowel control, including struggling to start, not feeling it happen, or leaking
- Sudden weakness in both legs
- Loss of sexual function alongside any of the above
That combination can indicate cauda equina syndrome, which is a surgical emergency and time matters. It is uncommon. It is not something to sit on for a fortnight to see how it goes.
Progressive weakness in one leg, foot drop, or symptoms that are getting rapidly worse rather than staying stable also need proper assessment quickly rather than eventually.
Why "wear and tear" is not a plan
Here is the honest position on scans.
If you take a hundred people over sixty with no back pain whatsoever and put them all in an MRI scanner, a large proportion will show degenerative change, narrowing, disc bulges, all of it. Their backs look worn out on paper. They feel fine.
Which means finding wear and tear on a scan tells you almost nothing on its own. Nearly everyone your age has it. The question is not whether your spine shows age-related change. It is whether that change is what is causing your symptoms, at which level, on which side, and what your spine does when you actually move.
That is a clinical question. It cannot be answered by a report and it cannot be answered by your age. It gets answered by someone examining you properly, watching you walk, testing what your nerves are doing, and matching the pattern of your symptoms to what they find.
"You are sixty-eight, what do you expect" is not a diagnosis. It is a shrug with a stethoscope on.
What can actually be done
Stenosis is mechanical, and mechanical problems have mechanical answers.
Once we know which level is involved and what is driving the narrowing, there are real options. Targeted decompression of the specific segment. Work on the mobility of the joints above and below, which are often taking the load. Building tolerance to extension so that standing upright stops being the enemy. Strengthening the muscles that support the segment so it can hold its own space rather than relying on a trolley to do it.
For the right patient, IDD Therapy is one of the tools we use. It applies a controlled distraction force to one specific spinal segment, opening it and taking pressure off the structures inside. It is not a fit for everyone with leg pain and we will tell you plainly if it is not right for you. It is one option among several, chosen on the basis of what the assessment finds, not on the basis of what we happen to own.
Surgery has its place, and for some people it is the correct answer. Most people are not there, and most have never been given a proper go at anything else first.
What does not work is being told it is your age and sent away.
What to do next
If you have read the list of classic signs and found yourself nodding, the useful next step is not another scan. It is a proper assessment. Someone who watches how you walk, works out what position does to your symptoms, checks your nerves and your circulation, and tells you what is actually going on in language you can use.
You may have been living around this for years. Planning routes by where the benches are. Choosing the trolley over the basket. Deciding you are not going to that thing because of the standing.
That is not something you have to accept because of a number on your birth certificate.
