Back pain after a busy day: stop before it stops you

The sun is out on Saturday, your back feels fine for once, and you clear the garage in one go: the boxes, the bikes, the bags for the tip. On Sunday morning you get out of bed in one stiff piece, and Monday isn't much better.

If that sounds familiar, look at the size of the jump before you blame the job. To avoid paying for a busy day, decide where you'll stop before you start, while you could still do a bit more, and leave the rest for tomorrow. Before a big day you can see coming, do a smaller version of the job in the days before.

Phil Sizer is the pain health and wellbeing coach at Pain Association Scotland. In a short video for the organization, Sizer describes a trap many people with long-lasting pain know: "a lot of people keep pushing themselves to their limit and then crash out," until it becomes "a boom and a bust" (0:42 to 0:52). The answer is a word many of them dislike, pacing, and a definition that sticks: "It really means stopping before your body stops you" (Pain Association Scotland, 2019, 1:27).

Sizer is talking about long-lasting pain of any kind, not only backs, and the advice comes from coaching practice, not a study. The research on activity and back pain points the same way.

Why a big day hits your back

1. Backs cope with what they're used to

A 2011 review gathered ten years of studies, 36 in all, on physical activity and low back pain. Intense effort in sport or exercise went with about 1.3 to 1.9 times the odds of back pain. Everyday activity went the other way: in one study, an hour a day of leisure activity went with lower odds of sick leave for back or neck pain (0.39), and in another, gardening went with lower odds of back pain (0.55) (Heneweer et al., 2011). The same review found regular home improvement work going with more back pain in one study, so the picture is mixed, and these are links from studies of different kinds, not proof of cause.

So the garden isn't the enemy. In the program's words, backs cope with what they're used to, and the jump is what goes with flares. A jump can also follow a quiet spell: a week of resting a sore back, then a full day of jobs, is a jump too.

Greg Lehman, a physiotherapist and pain educator who also sells courses on pain science, puts it this way in a free guidebook: "We get pain or injured when we do too much too soon for us at that point in time. And what is 'too much too soon' is something that changes" (Recovery Strategies, p. 32). The guidebook's example: "If you were a cyclist 20 years ago but haven't ridden since it wouldn't be wise to start cycling as fast and far as you last rode."

2. The days before a bout count

One study asked 999 people in Sydney with a new bout of back pain what they'd done in the four days before it started, and compared that with their own ordinary days. Heavy loads and bursts of hard activity went with a higher risk of a new bout (Steffens et al., 2015). It's one study, and we give no figures from it because only its summary was available.

Here's what that looks like in practice. A desk worker who carries the shopping in twice a week and then moves house in a weekend is asking their back for much more than usual. A gardener who digs a little most weekends and digs the same bed in spring is not. Same job, different jump.

3. The boom-and-bust swing

On a good day, the back feels fine, so you keep going. The next day it pays, and a bad day stops you completely. Sizer says that over time, booming and busting means "the amount that we can achieve before pain stops us gradually gets less with time," and people start to link certain jobs with "inevitable pain" (0:52 to 1:17). That's Sizer's account from coaching, offered in the video as "the science of pain." The studies are less tidy.

In a 2011 survey of 132 Dutch adults who'd had muscle or joint pain for more than three months, feeling obliged to finish everything, however bad they felt, went with more limits in daily life and lower mood. Avoiding activity went with more limits too (Kindermans et al., 2011). A 2012 review of 41 studies found the same at both ends: avoiding activity and overdoing it were both linked with poorer outcomes (Andrews et al., 2012). Both were snapshots, so they show links, not causes. And when people were taught to pace themselves in trials, it didn't lower their pain, though it helped with stiffness, tiredness and the swings in how much they did (Guy et al., 2019).

So evening out your days won't turn the pain down by itself. What the trials found it can ease is the swing in how much you do, and with it the days spent paying for the last one.

How to stop before it stops you

4. Check for warning signs first

Serious causes of back pain are rare, but a few signs mean you should get checked. If any of these start, get help.

Get medical help straight away:

• Trouble peeing, or leaking pee or poo without meaning to
• Numbness around your genitals or bottom, or sex feeling different
• Both legs weak, numb or tingly, or you can't walk because of the pain
• Pain after a serious fall, accident or blow
• Chest pain or trouble breathing with it; or new pain far worse than before, or getting worse fast

See a doctor first:

• A fever, or feeling hot, shivery or unwell
• Cancer in the past, or weight lost without trying
• Pain worse at night or unchanged by moving or resting; high between the shoulder blades; one leg weak or numb

If any sign in the second group applies to you, see a doctor before you build up to bigger days; until then, keep your days to their usual size. If a new flare isn't getting better after a few weeks, keeps getting worse, or worries you, see a doctor.

5. Decide where you'll stop before you start

This is the first step the 1h Protocol to Manage Back Pain gives anyone whose back days follow this pattern, which it calls the Big Day: before the next big day, cut it into pieces. "Decide where you'll stop while you could still do a bit more, and what moves to tomorrow."

Sizer's version is a number, offered with care: "instead of going to 100% of capacity work to 70. Now 70 isn't a dial that comes up in your head. It's not an exact number. It just basically means doing something such that you can still do a little bit more" (1:40 to 1:57). It's one coach's rule of thumb, not a tested figure. "It sounds simple," Sizer adds, "but a lot of people find that extraordinarily hard to do."

Stopping early on a good day feels like a waste, which is why the decision belongs before you start.

"It really means stopping before your body stops you." Phil Sizer

6. Write the stopping point on the job

A decision in your head is easy to overrule at four in the afternoon. So put it somewhere you'll see it: the last box marked "tomorrow," a stake at the end of the stretch you'll dig, a line on the list, a note on the last shelf to sort. When you reach it, stop, even if you feel fine.

If you can't leave a job half done, split it into two shorter goes with a break between. Heavy parts can be split too: two trips with half the load, swap sides, or ask for help. Our guide to lifting with back pain covers the heavy bits.

7. Before a big day you can see coming, do a smaller version first

Some big days come with warning: a move, a spring clean, a family visit, a holiday with bags to carry. In the days before, do a smaller version of the job. Dig one row this weekend before the whole bed next weekend; carry a couple of boxes up the stairs midweek before the move. Australia's care standard for low back pain gives the same pace for people whose pain is worse after activity: "take things a little easier at first and gradually build up over a few days or weeks" (ACSQHC, 2022). If any of the warning signs above apply to you, see a doctor before you build up.

No warning? Then make the day itself smaller, with the stopping point and the split from steps 5 and 6.

8. On good days, do a bit more than a bad day, not everything

The catch-up version of the Big Day isn't one event: it's every good day spent clearing the backlog. The program's line for it: on a good day, stop at the plan; on a bad day, keep a smaller version. Not none. A short walk, getting dressed, one job you'd normally do. Staying active is what back pain guidance asks on bad days too: "Do not wait for all the pain to be gone before you start moving" (ACSQHC, 2022). Our guides on what to do in a flare and walking for back pain cover the bad days.

9. Make it a choice

Sizer is clear that this isn't a rulebook. Sometimes going to the limit is worth it, and the point is to choose it: if you do and you're laid up the next day, you can think "well that was worth it" (2:24 to 2:33). One woman Sizer worked with disliked the word pacing so much that they called it "choicing" instead. Pick the days that earn it, and plan the day after.

Back to the garage

Next time the garage is waiting, you decide before you start: the bikes and the boxes today, the bags for the tip tomorrow. You mark the last box, and you stop there while you could still do more. As Sizer says, it sounds simple, and the practice is doing it on a good day.

To build this around your own back days, try the 1h Protocol to Manage Back Pain, a program of practical education. Its free first chapter starts with a quick check for warning signs, then finds your back-day pattern (the Brace, the Big Day, the Long Still Day, the Volume Knob, or the Tune-up) and gives you one thing to do tomorrow; for the Big Day, it's cutting the next big day into pieces. The full program takes about an hour: you see the Alarm, the Guard and the Load in your own last bad day, walk one back day and fit seven habits to your own times, and plan the first hours of a flare and the days after it. You leave with two or three things to start now, each with an alternative for harder days, a flare card for your lock screen, and fourteen days to try it, with a sheet, reviews on days 7, 14 and 30, and four one-tap check-ins by email if you're signed in.

Frequently asked questions

Why does my back hurt the day after gardening or cleaning?

Often because the day was bigger than your back is used to. In studies, intense effort went with more back pain and regular everyday activity, gardening included, with less (Heneweer et al., 2011). If the pain started after a fall or an accident, or comes with any of the warning signs above, get checked.

What is boom and bust with back pain?

It's the swing between doing everything on a good day and very little on the bad day that follows. Phil Sizer describes people who "keep pushing themselves to their limit and then crash out" (Pain Association Scotland, 2019, 0:42). In studies of long-lasting pain, both overdoing and avoiding went with more limits in daily life.

How do I know when to stop?

Decide before you start, not when it hurts. Sizer suggests working to about 70% of what you could do, "such that you can still do a little bit more" (1:53); it's a rule of thumb, not an exact number. Mark the stopping point on the job so you see it.

Can I still do big jobs with back pain?

Yes, with the jump made smaller. Do a smaller version of the job in the days before, split the day into pieces, and move what's left to tomorrow. Nobody can promise a big job won't hurt; the aim is a smaller jump. If you have a warning sign, see a doctor before you build up.

Does evening out my days reduce pain?

Not by itself, as far as the trials show. A 2019 review found that learning to pace didn't lower pain, though it helped with stiffness, tiredness and the swings in activity (Guy et al., 2019). Its value is in the swing, not the pain score.
