Frequently asked questions

Is it safe to exercise, walk, or lift with this — or am I making it worse?

This is probably the single biggest source of anxiety in back pain, and the honest answer is that for most people, staying as active as you can is safer than resting. Prolonged bed rest doesn't protect a back; it deconditions it, and deconditioning makes the next flare more likely, not less. Fear of movement is also, on its own, one of the things that keeps chronic pain going.

But "just push through it" isn't the whole answer either, and this is where a lot of advice quietly fails people. When a nerve is involved, there's a real, useful distinction: pain that spreads further down the leg, or that sharpens, is a signal you're aggravating something. Pain that eases, or draws back toward the spine, is usually a good sign — a pattern called centralization. That difference matters more than any general rule about pain being "fine" or not.

If you want a fuller answer for your specific situation, the quick triage tool asks what your pain does when you move and points you toward what's actually appropriate rather than a generic rule.

How do I choose between all these programs and methods?

This is genuinely the question this whole site exists to answer, so it's worth a real answer rather than a shrug. The short version: most of these are not competing for the same job. McKenzie is a diagnostic-and-self-treatment system for finding a directional preference. McGill is about removing what provokes you and building endurance. General strength training builds long-term capacity. Cognitive Functional Therapy addresses fear and movement together. They solve different problems, and the useful question isn't "which is best" but "which problem do I actually have, right now."

Two things narrow the field faster than reading every entry. First, work out what kind of pain you likely have — the kinds of back pain page distinguishes non-specific pain from disc problems, facet or SI joint pain, stenosis, and a few others, because the right approach genuinely differs between them. Second, be honest about what stage you're at — a fresh flare, active rehab, the long haul, or a problem that isn't resolving — since an approach that's right for rebuilding capacity can be the wrong one mid-flare, and vice versa.

It's also completely normal to use more than one approach, in sequence or together — say, McKenzie during a flare, then general strength training once things settle. Committing permanently to one method like a religion is not how most people who get better actually do it.

Do I need an MRI or surgery?

Probably not, and this is one of the more evidence-backed, counterintuitive answers on this page. Clinical guidelines consistently recommend against routine imaging for back pain when there are no red-flag symptoms, because scan findings frequently don't explain the pain and don't change what treatment actually helps. Disc degeneration, bulges, and even annular tears show up constantly on the scans of people with no pain at all — see the disc and annular tear entries for why a scary-sounding report often isn't the sentence it sounds like.

Imaging earns its place when there's a specific reason to look: significant trauma, unexplained weight loss, fever, a history of cancer, progressive weakness, or symptoms not settling after a genuine trial of conservative care. Outside of those, an early scan tends to add anxiety and sometimes unnecessary intervention without improving the outcome.

Surgery follows a similar logic. For the large majority of back pain, it's not the first move and doesn't need to be — most herniations shrink on their own, most non-specific pain settles with conservative care. Surgery earns a real place for a specific minority: a confirmed structural problem, most often a nerve genuinely compressed by a herniation or spinal stenosis, that hasn't improved after a fair trial of conservative treatment, or urgently for progressive weakness or cauda equina symptoms. The surgical entries on this site go into when each option actually applies.

How long does this take to heal? Will it ever go away? Is this permanent?

The honest, and genuinely reassuring, statistical picture: most acute back pain improves substantially within a few weeks. Most disc herniations — including fairly large ones — shrink and settle on their own over weeks to months, sometimes with the biggest ones resolving fastest, since the body treats an exposed fragment as something to break down and clear. A frightening-looking scan report is not a permanent diagnosis of doom; it's a snapshot, often of something that's already on its way to resolving.

That said, catastrophizing about permanence is common and understandable, especially mid-flare when the pain is all you can think about. It's worth separating the immediate flare (which usually settles faster than it feels like it will) from the underlying tendency to have episodes, which for some people is genuinely more persistent or recurrent. That second group is real, not imagined, and it's exactly what the "long-haul" stage and the healing and prevention side of this guide are for — the goal there shifts from "make this go away" to "build enough capacity and understanding that it stops running your life."

If you want a feel for your own likely trajectory rather than a generic average, the triage tool asks how long you've had it and what's happening now, and answers accordingly.

NSAIDs and painkillers aren't working — what actually helps nerve pain?

This is a genuinely useful thing to know and not something most people are told: the evidence for NSAIDs specifically in nerve-related leg pain (sciatica) is surprisingly weak. A Cochrane review found NSAIDs no more effective than placebo for pain reduction in sciatica specifically, even though they're the default reach for almost any back pain. NSAIDs are built for inflammatory, tissue-type pain; nerve pain often behaves differently. Commonly prescribed nerve-pain medications like gabapentin and pregabalin also have thinner evidence for sciatica specifically than their popularity suggests, and can come with side effects worth weighing.

None of that means stop what you've been prescribed — that's a conversation with your doctor, not a website. What it does mean is that if painkillers alone aren't touching it, that's not a sign you're broken or that nothing will help; it may just mean the tool doesn't fit the job. Approaches on this site aimed more specifically at nerve-related pain include:

• McKenzie Method — finding a direction that draws symptoms back out of the leg
• TENS — drug-free symptom relief you control yourself
• Epidural steroid injections — calming inflammation right at the nerve
• Cognitive Functional Therapy and BackUnbroken — for pain that has outlasted the original injury and become a sensitized nervous-system pattern

Worth raising the specific phrase "nerve-related" or "radicular" with your doctor or pharmacist — the treatment conversation genuinely differs from ordinary muscular back pain.

I'm in a flare right now — what do I do today?

First, quickly rule out the situations that need urgent attention rather than home care: numbness around the groin or inner thighs, loss of bladder or bowel control, or leg weakness that's getting worse. If any of those apply, get seen today rather than reading further.

If none of those apply, here's what actually helps in the first day or two:

• Don't go to bed for days — prolonged rest makes this worse, not better
• Move gently and often, in short bouts, rather than one long session or none at all
• Find a position that eases things and use it — for many people that's lying with knees bent, or standing and walking over sitting
• Heat or ice, whichever feels better to you — the evidence doesn't strongly favour one
• Over-the-counter pain relief, used as directed, can make it easier to keep moving
• Avoid anything that sends pain further down a leg; ease off if it happens

Being frightened in the middle of a bad flare is completely normal, and it doesn't mean something is seriously wrong — most acute back pain, even when it feels catastrophic on day one, improves substantially within a couple of weeks. Once the sharpest edge has passed, the triage tool can point you toward what fits your specific situation next.
