Working Through Pain: When It Helps and When It Harms

Whether working through pain helps or hurts depends almost entirely on what kind of pain you’re dealing with and what “working through it” looks like. For acute injuries with structural damage, pushing ahead often makes things worse. For many chronic pain conditions, tendon problems, and general musculoskeletal soreness, carefully maintained activity can be one of the best things you do. The complication is that your brain isn’t a reliable narrator when it comes to telling you which situation you’re in. Pain and tissue damage are more loosely connected than most people realize, which makes the instinct to simply stop whenever something hurts a blunt and sometimes counterproductive strategy.

Why Exercise Reduces Pain in the First Place

One reason the “push through it” advice persists is that physical activity genuinely does turn down the volume on pain, at least temporarily. This phenomenon, called exercise-induced hypoalgesia, is well documented across different types of exercise. In one study, participants who performed an isometric exercise (a sustained muscle contraction) during heat-pain stimulation rated the pain significantly lower than those who simply rested. The pain-reducing effect of the exercise was comparable in size to a placebo manipulation, suggesting it’s a reliable biological response rather than just a distraction effect.

The mechanism doesn’t appear to be what most people assume. Research has shown that endocannabinoid concentrations in the blood rise significantly after exercise, and when an opioid-blocking drug was administered before isometric exercise, the pain relief still occurred. That points toward the body’s endocannabinoid system, not its endorphin system, as a key player in exercise-related pain relief during at least some types of activity.¹ Your body, in other words, produces its own cannabis-like molecules when you exercise, and those molecules dampen pain signaling.

This built-in pain-relief system makes evolutionary sense. An organism that became completely incapacitated by pain during a physically demanding situation, like fleeing a predator or foraging while mildly injured, wouldn’t survive long. Pain can be amplified or inhibited from the top down, depending on what the situation demands.² The ability to dial pain down during activity isn’t a glitch; it’s a feature. But it’s also one that can mislead you about the state of your tissues, which is where the complications begin.

Pain and Damage Are Not the Same Thing

The most important thing to understand about working through pain is that pain perception and actual tissue injury are separable. You can have severe trauma with little pain, as documented in cases of major accidents where victims remain calm and apparently pain-free despite serious injuries. And you can have significant pain with no detectable tissue damage at all, as seen in many chronic pain conditions.³

This disconnect matters practically because the default assumption, “if it hurts, something must be breaking,” drives a lot of decisions that end up being harmful. People with chronic low back pain, for instance, often drastically reduce activity because they believe movement is causing further injury. But in a controlled trial comparing exercise-based treatment (“stay active”) against rest-based treatment (“reduce load”) in patients with persistent back pain and visible spinal changes on MRI, there was no difference in outcomes between the two groups.⁴ The people who stayed active didn’t get worse. Their pain wasn’t a signal that movement was causing damage.

Where the disconnect becomes dangerous is at the other end: when real structural harm is occurring but you’ve become skilled at ignoring the signals or your nervous system is suppressing them during activity. Athletes are particularly vulnerable here, and we’ll get to why shortly.

The Cost of Avoiding Pain Entirely

If the link between pain and damage is loose, then organizing your life around pain avoidance can backfire. Research on what’s called the fear-avoidance model shows exactly this. A large meta-analysis found that fear of pain, catastrophic thinking about pain, and hypervigilance toward pain all had medium- to large-sized associations with greater disability, depression, anxiety, and pain intensity.⁵ A separate prospective study found that avoidance behavior was the single strongest predictor of worsening functional disability over three months, even more than fear of pain itself.⁶

The pattern is self-reinforcing. Pain triggers fear, fear triggers avoidance, avoidance leads to deconditioning and social withdrawal, deconditioning makes movement more painful, and the cycle tightens. Breaking it usually requires doing the thing that feels counterintuitive: moving into the pain, carefully, with appropriate guidance. This is one of the strongest arguments for working through pain, but it applies specifically to chronic pain where tissue damage is either absent or stable, not to acute injuries where rest is genuinely protective.

When Pushing Through Actually Helps Recovery

For certain injuries, structured activity during the painful phase appears to be actively therapeutic. A randomized controlled trial of patients with Achilles tendinopathy, a painful tendon condition, found that continuing to run and jump using a pain-monitoring approach produced significant improvements with no detectable negative effects. The protocol gradually increased load on the tendon and calf muscle, and patients used their pain levels as a real-time guide for how hard to push.⁷

The tendon biology behind this helps explain why complete rest can actually slow recovery. Tendons respond to mechanical load: it’s what drives their normal maintenance and repair. But if you remove load entirely, the tendon doesn’t just sit idle. Its cellular environment changes, and the structural matrix that gives the tendon its strength can deteriorate.⁸ The flip side is that excessive load overwhelms the repair process, disrupting collagen organization and triggering cell death.⁹ The goal, then, is finding the loading sweet spot: enough to stimulate healing, not so much that you’re outpacing repair.

The pain-monitoring model used in the Achilles study offers a practical framework. Rather than asking “does this hurt at all?” (which would shut down virtually any rehabilitation exercise), it asks “how much does this hurt, and does the pain settle within a reasonable time after stopping?” Mild to moderate pain during controlled exercise that subsides afterward is generally tolerable. Pain that escalates during the session or lingers for hours afterward is a signal to back off.

When Pushing Through Causes Long-Term Harm

The case for working through pain has a hard limit, and the evidence for the consequences of exceeding it is sobering. A large cross-sectional study found that people who had played sport while injured had roughly double the odds of persistent joint pain and nearly double the odds of osteoarthritis compared to those who had not.¹⁰ They also reported worse physical and mental health-related quality of life. This wasn’t about exercising with chronic aches; it was about playing through actual injuries, and the joint consequences lasted well beyond the sporting years.

After major joint injuries like ACL tears, returning to high-level sport often accelerates degenerative changes. Some athletic careers are shortened not because of talent but because the knee can no longer tolerate repeated high loads, with recurrent swelling, pain, and functional limitations suggesting premature joint deterioration.¹¹ The “tough it out” culture in competitive sports, where pain tolerance is treated as a virtue, can mask early signs of problems that become irreversible if ignored long enough.

The distinction that matters is between pain arising from a condition where controlled loading promotes healing (like a tendinopathy or stable chronic back pain) and pain from an acute structural injury or progressive joint damage where continued loading is eroding tissue faster than it can repair. The former rewards persistence. The latter punishes it.

How Your Body Quietly Compensates

Even when pain doesn’t stop you from performing a task, it changes how your body performs it. Research on pain-induced motor changes shows that when one muscle is painful, the nervous system redistributes workload: the painful muscle’s activity drops while nearby muscles pick up the slack.¹² In one experiment, inducing pain in the biceps during elbow flexion led to a roughly 23% drop in biceps activity, while the upper trapezius ramped up by about 45% to compensate.

A systematic review confirmed this pattern across many studies: pain inhibits the affected muscle and its synergists, especially during stronger contractions, but task performance often remains intact because the body redistributes the effort.¹³ You can still do the job, but you’re doing it with an altered movement pattern. In the short term, that’s a clever adaptation. Over weeks or months of working through pain, those compensatory patterns can overload the muscles and joints that weren’t designed to bear the extra burden, creating new problems.

Athletes Process Pain Differently

If you’ve ever watched someone finish a marathon on what turns out to be a stress fracture, the question of whether athletes are just tougher isn’t idle curiosity. They genuinely do process pain differently. A systematic review and meta-analysis found that athletes demonstrated substantially greater pain tolerance than non-athletes, with a large effect size, and reported less pain intensity in experimental settings.¹⁴ Pain thresholds were also higher in athletes, though the difference was smaller and became non-significant after removing studies with methodological concerns.¹⁵

The type of sport matters. Endurance athletes, like cross-country skiers and distance runners, tolerate cold pain better than both team-sport athletes and non-athletes, and they report lower pain intensity to thermal stimulation.¹⁶ Whether this reflects self-selection (people who naturally tolerate pain better gravitate toward endurance sports) or training-induced adaptation (years of discomfort literally rewire pain processing) is still debated. It’s likely both.

The practical edge of athletic pain tolerance is that the same signal intensity that would stop most people doesn’t stop an athlete. That capacity is what makes elite performance possible, and also what makes athletes vulnerable to the kind of damage described in the section above. The very trait that enables working through pain also makes it harder to know when you shouldn’t.

Working Through Pain at a Desk

“Working through pain” doesn’t just mean physical training or rehabilitation. For most people, it means sitting at a desk with a headache, a sore back, or a stiff neck and trying to get through the workday. The research on this kind of pain-at-work paints a clear picture: it costs you, and it costs your employer.

A study of Japanese full-time workers found that moderate to severe pain was significantly associated with both absenteeism and presenteeism (being at work but functioning poorly).¹⁷ A separate study of workers with chronic pain found that presenteeism averaged over 44%, meaning people were performing at roughly half capacity, and that each increase in pain severity was associated with further drops in work productivity and greater difficulty with physically demanding tasks.¹⁸

It’s not just the pain itself eroding performance. Catastrophic thinking about pain, depression, and anxiety all independently drag down work output. A study using detailed statistical modeling found that depression and cognitive difficulties were significantly linked to overall work performance, while pain, anxiety, and limitations in daily activities predicted how someone performed relative to coworkers.¹⁹ Pain at work, in other words, rarely stays a purely physical problem.

Ergonomic setup makes a measurable difference. Among laboratory workers performing repetitive tasks, those who alternated between sitting and standing reported significantly less pain than those who only stood. Standing-only workers had roughly triple the odds of neck pain and more than double the odds of upper-back pain compared to those who varied their posture. Workers who felt unable to take breaks or slow their pace were more likely to have pain at multiple body sites.²⁰ High psychological demands combined with low job control further amplified musculoskeletal symptoms, with neck and shoulder complaints roughly tripling under those conditions for women.²¹

Getting Back to Work After Pain Sidelines You

When chronic pain does pull someone out of work, returning isn’t just a matter of the pain resolving. An evidence review found that workplace interventions significantly reduced time away from work for musculoskeletal and pain-related conditions, but only when the programs spanned multiple domains, combining physical or health-related elements with workplace modifications and psychological or behavioral support.²² Addressing just one dimension rarely worked.

For early-stage musculoskeletal pain, stepped-care approaches where treatment starts simple and escalates only if needed showed moderate evidence of effectiveness at promoting return to work within a year. Simple case management alone did not.²³ The practical takeaway is that early, structured, and multi-layered intervention beats both doing nothing and doing one thing well. A job coach alone or physical therapy alone is less effective than combining the two with ergonomic adjustments and psychological support.

Pain Acceptance as a Practical Skill

The psychological dimension of working through pain deserves its own discussion because it changes outcomes in ways that are measurable and, frankly, larger than many people expect. A meta-analysis found that chronic pain acceptance, which means willingness to experience pain without trying to control or avoid it, was associated with a moderate reduction in pain-related disability.²⁴

A prospective study followed patients with chronic pain over time and found that those who reported greater acceptance at the start of the study had better emotional, social, and physical functioning later, along with less medication use and better work status.²⁵ Acceptance-based therapy programs have shown clinically significant improvements in disability, depression, and pain-related anxiety, with changes in psychological flexibility mediating the improvements.²⁶

This isn’t about pretending pain doesn’t exist or white-knuckling through suffering. Acceptance in this context means shifting from “I need the pain to stop before I can live my life” to “I can do meaningful things even with this pain present.” It’s the psychological counterpart to the physical loading strategies used in tendon rehabilitation: instead of waiting for the signal to clear, you learn to function within it.

When the Pain System Itself Goes Wrong

One reason chronic pain so often defies the “work through it or rest” binary is that, over time, the nervous system can change in ways that make pain self-sustaining. Central sensitization is a state where neurons in the spinal cord and brain become hyperexcitable, amplifying signals that would normally be harmless and generating pain from inputs that wouldn’t ordinarily register.²⁷ A related process involves the weakening of the brain’s own pain-suppressing circuits. Evidence suggests that when the descending pathways that normally dampen pain signals lose their effectiveness, the risk of acute pain becoming chronic increases.²⁸

For someone in this state, “working through pain” means something different than it does for a weekend runner with a sore knee. The pain isn’t reliably tracking tissue status, so neither “keep going, it’s fine” nor “stop, something is broken” fully applies. Treatment typically involves gradually retraining the nervous system’s responses through graded activity, psychological approaches, and sometimes medication, rather than simply loading through it or resting until it resolves.

How Age Changes Pain Relief From Exercise

The pain-relieving effect of exercise isn’t uniform across the lifespan. A study comparing younger and older adults found clear age differences in exercise-induced hypoalgesia: younger adults experienced significantly greater pain reduction after both isometric and aerobic exercise than older adults did.²⁹ This means the built-in reward system that makes physical activity feel like it’s “helping” the pain works less efficiently as you get older, which may partly explain why older adults are more likely to avoid activity when something hurts.

The clinical implication is that older adults working through pain may need more external support, whether from structured programs, manual therapy, or psychological strategies, because their internal pain-dampening system provides less of a tailwind. It doesn’t mean exercise is less beneficial for them; the tissue-level and cardiovascular benefits are just as real. But the immediate pain-relief payoff that makes younger people feel good about pushing through may simply be weaker.

The NSAID Shortcut and Its Trade-offs

When working through pain, the temptation to reach for anti-inflammatory drugs is obvious. Pop an ibuprofen before the gym and the pain drops enough to train normally. But the evidence on long-term NSAID use during training suggests this shortcut has a price. A review of the available research found that chronic use of these drugs can interfere with muscle regeneration, satellite cell activity (the cells that repair and grow muscle fibers), connective tissue remodeling, and even gut barrier integrity. Young people training at high volumes may be especially susceptible to blunted adaptation.³⁰

Inflammation, it turns out, isn’t just a symptom to suppress. It’s part of the repair and adaptation cascade. The soreness you feel after hard exercise reflects an inflammatory process that, when allowed to proceed, drives muscle rebuilding and tendon strengthening. Chronically blocking that process with NSAIDs may let you train through discomfort today while quietly undermining the structural gains you’re training for. Occasional use for acute flare-ups is a different matter than daily prophylactic dosing, and the distinction matters more than most gym-goers realize.
