The most common cause of disability worldwide. Usually nonspecific, with no single structural cause, and imaging findings are common in people with no pain at all2. Staying active and exercise have the best evidence3; nutrition plays a supporting role through weight and vitamin D5.

Low back and neck pain together represent the leading cause of disability worldwide. Most pain is "nonspecific," meaning no identifiable structural cause despite imaging findings2. The relationship between imaging findings (disc bulges, mild stenosis) and pain is weak; many asymptomatic adults have abnormal MRIs.
Acute pain (<4 weeks) is typically musculoskeletal, and in most cases it settles on its own, though for some people it continues and becomes chronic8. Subacute (4 to 12 weeks) and chronic (>12 weeks) pain involves central sensitization, the nervous system amplifying pain signals, beyond any tissue damage. This is why chronic spine pain doesn't always correlate with imaging or respond to surgery.
Most pain has multifactorial causes: postural strain, deconditioning, muscle imbalances, prolonged sitting, stress, poor sleep, obesity and central sensitization. Less commonly: disc herniation with nerve root compression, spinal stenosis or spondylolisthesis; rarely, serious causes (fracture, tumor, infection, "red flags"). Modern management emphasizes active treatment, not bed rest or imaging chasing.
Most common. <4 weeks. No identifiable structural cause. Most people recover well with simple care8. Avoid early imaging; it promotes harmful interventions.
Most pain is mechanical: it changes with posture and movement, and is often stiff after rest and eases as you get moving. Watch for red flags that warrant urgent evaluation.
| Symptom | What happens |
|---|---|
| Typical Pain Patterns | |
| Mechanical Pain | Worse with certain movements/positions, better with others. Stiff in mornings, improves with movement. Worse with prolonged sitting (low back) or computer use (neck). |
| Muscle Spasm | Painful muscle tightness, often after injury or overuse. You may lean or hold yourself crooked to avoid the pain. Limited range of motion. May feel "knotted" or twisted. |
| Stiffness & Reduced Range | Difficulty bending, rotating. Worse with inactivity. May limit daily activities. Improves with gentle movement and stretching. |
| Sleep Disturbance | Pain worsens at certain positions. Difficulty finding a comfortable position. Creates a vicious cycle: poor sleep amplifies pain perception. |
| Red Flags (Urgent Eval) | |
| Bladder / Bowel Dysfunction | Loss of control, urinary retention, saddle anesthesia (numbness in groin). Suggests cauda equina syndrome, a surgical emergency1. Call 911 or go to the emergency department now. |
| Progressive Weakness | Foot drop, leg weakness, loss of grip strength. Major neurologic deficit. Requires urgent imaging and possible surgery. |
| Fever, Weight Loss, History of Cancer | Raises concern for spinal infection, malignancy or metastases. Age >50 with new pain also warrants imaging. Don't dismiss. |
| Radiating Pain with Numbness | Sciatica: pain down leg, possibly with numbness/weakness. Cervical radiculopathy: pain down arm. May indicate nerve root compression. Evaluate especially if persistent. |
Most low back and neck pain has no single structural cause that a scan or test can find; the factors below raise the risk, and a few specific causes need to be ruled out8.
| Cause | How It Contributes to Low Back & Neck Pain | What Helps |
|---|---|---|
| Low physical activity | Low levels of physical activity are a risk factor for nonspecific low back pain8 | Staying active and exercise therapy, the best-supported treatments in the treatment section, and avoiding long periods in bed22 |
| Excess weight and smoking | Obesity and smoking are both risk factors for nonspecific low back pain8 | A healthy weight, with the eating pattern in the diet section, and stopping smoking8 |
| Physical strain at work | High physical stress at work is a risk factor for nonspecific low back pain8 | Reducing strain during physical work and making ergonomic changes to the workplace8 |
| Posture, sleeping position and neck injury | The most common causes of neck pain are the neck locking in an awkward position during sleep, poor posture such as long hours at a desk, a pinched nerve and injury such as whiplash23 | Keeping the neck moving rather than wearing a collar, changing position often at a desk, a low firm pillow and heat or cold packs wrapped in a towel23 |
| A pinched nerve or a narrowed spine | A slipped disc or narrowing of the spinal canal can involve a spinal nerve root, sending pain, numbness, tingling or weakness down a leg or arm822 | Examination first; a scan when a red flag is present or nerve symptoms persist after about six weeks of good conservative care16, and specific treatments, including surgery, for selected cases |
| Serious causes, rarely | Very rarely back pain is a sign of a broken bone, cancer or an infection, and it can also be referred from organs such as the kidney or from an aortic aneurysm228 | Urgent medical assessment rather than self-care, as When to Seek Care sets out |
| Test | What it shows |
|---|---|
| Clinical Assessment | |
| History & Physical Examination | Most important assessment. Identifies red flags, assesses nerve involvement, evaluates psychosocial factors. Most pain diagnosed without imaging. |
| Neurologic Exam | Reflexes, muscle strength, sensation, gait. Identifies nerve root or spinal cord involvement. Critical for treatment decisions. |
| Functional Assessment | Range of motion, posture, gait, ability to perform daily activities. Often more useful than imaging for treatment planning. |
| Psychosocial Screening | STarT Back screening, anxiety/depression screens. High psychosocial risk predicts chronicity. Drives treatment intensity decisions. |
| When to Image | |
| X-Ray (Limited Role) | For trauma, suspected fracture, spondylolisthesis. Not routine for nonspecific pain. Findings often unrelated to pain. |
| MRI (Selected Cases) | For red flags, persistent radiculopathy >6 weeks, surgical consideration. Not routine; findings of disc bulges and mild stenosis are common in pain-free adults. |
| Don't Over-Image | Early imaging in nonspecific pain is associated with worse outcomes, more interventions and more surgery2. Choosing Wisely recommendations advise against routine imaging. |
| Labs (Red Flag Workup) | CBC, ESR, CRP if infection or inflammatory cause suspected. Vitamin D level where deficiency is suspected, for bone and muscle health5. |

Anti-inflammatory foods for spine pain, and what to avoid
| What to eat or do | Details |
|---|---|
| โ Prioritize: | |
| Fatty Fish (2 to 3x/week) | Wild salmon, sardines, Atlantic mackerel. Omega-3 EPA/DHA anti-inflammatory. |
| Colorful Anti-Inflammatory Vegetables | Leafy greens, cruciferous, beets, peppers. |
| Extra-Virgin Olive Oil | Contains oleocanthal, which acts like a very weak ibuprofen in laboratory studies. 2 to 4 tbsp daily as primary fat. |
| Turmeric & Ginger | Anti-inflammatory spices. Use generously in cooking. |
| Bone Broth & Collagen | Provides amino acids for connective tissue. Glycine for sleep quality. |
| โ Avoid: | |
| Refined Sugar / Refined Carbs | A healthy diet keeps free sugars low9. Cut down on sodas, sweets, white bread, pastries. |
| Ultra-Processed Foods | Pro-inflammatory. Trans fats, additives, low nutrient density. Replace with whole foods. |
| Excessive Red & Processed Meats | Pro-inflammatory in excess. Limit red meat <3 servings/week; eliminate processed meats (bacon, sausage, deli meats). |
| Tobacco | A risk factor for low back pain, and not smoking helps prevent further episodes8. |
| Heavy Alcohol | Disrupts sleep needed for pain modulation. Inflammatory effects. Interferes with medications. Limit to no more than 1 drink a day. |
Evidence for supplements in back pain is limited, and nutrition's role is supporting rather than treating5. Mind-body and movement are the foundation; supplements are adjunctive.
| Supplement | What it is for | Typical range | Timing | Notes & cautions |
|---|---|---|---|---|
| Vitamin D3 | Corrects a deficiency, which matters for bone and muscle5. Observational studies link low vitamin D with low back pain26; this does not show that supplementing relieves pain. | Set the dose with your clinician; most adults need no blood test first | With fat meal | The adult upper intake level is 4,000 IU/day. |
| Magnesium | Muscle relaxation, reduced neural excitability. For muscle cramps, a Cochrane review found supplements unlikely to help older adults10. | 200 to 400 mg/day | Evening | Improves sleep quality. The top of this range is above the 350 mg/day upper intake level for supplemental magnesium; above that, diarrhea is common. With kidney disease, take it only on your clinician's advice. |
| Omega-3 (EPA/DHA) | Anti-inflammatory. Reduces inflammatory mediators driving pain. | 2,000 to 3,000 mg EPA+DHA/day | With fat meal | Tell your clinician if you take an anticoagulant or antiplatelet medicine, and before any planned procedure. In heart trials, fish oil supplements raised the risk of atrial fibrillation, an irregular heartbeat, more so above 1 g a day25, so check this dose with your clinician first. |
| Curcumin | Anti-inflammatory. Early trial evidence is mainly in knee osteoarthritis11; in back pain the only trials found test it combined with boswellia (see Boswellia)12. Direct comparisons against anti-inflammatory medication are limited. | 500 to 1,500 mg/day | With fat meal | Liver damage has been reported with high-bioavailability forms: stop and seek advice for dark urine, yellowing skin, nausea or unusual tiredness11. |
| Boswellia serrata | 5-LOX inhibitor. Reduces inflammatory leukotrienes. Evidence in spine pain is limited. | 300 to 400 mg, 3x/day (60% boswellic acids) | With meals | Two small placebo-controlled trials of boswellia combined with curcumin reported less low back pain, but neither tested whether the combination beats either one alone12. |
| Glucosamine | A randomized trial in chronic low back pain with degenerative arthritis found no benefit over placebo7. | Not recommended for low back pain (the trial used 1,500 mg of glucosamine a day) | Not applicable | Not recommended on this evidence. |
| PEA (Palmitoylethanolamide) | Endogenous fatty acid amide. A meta-analysis across mixed pain conditions found more pain reduction than inactive controls, from few trials of often poor quality13. | 600 to 1,200 mg/day | Empty stomach | Larger, well-designed trials are still needed13. |
Most back and neck pain improves within weeks, though it can last longer or come back22.
Call 911 or go to the emergency department now for numbness around the genitals or buttocks, new trouble passing or controlling urine or stool, or weakness or numbness in both legs, which are signs of cauda equina syndrome2216. Get urgent medical assessment for pain with fever or feeling unwell, a history of cancer, unexplained weight loss, pain after a significant fall or injury, or weakness in a leg or arm that is getting worse24.

Most spine pain responds to active treatment: exercise, mind-body therapies, anti-inflammatory nutrition and sleep optimization. Avoid early imaging unless there are red flags. Opioids are not recommended for chronic pain; if you already take one, do not stop or cut down without your prescriber. Be cautious about elective spine surgery for nonspecific chronic pain. Modern evidence strongly supports the active, multimodal approach.

Last reviewed October 20, 2026. Supplement entries are cross-checked against the NIH National Center for Complementary and Integrative Health and the Linus Pauling Institute Micronutrient Information Center.6 Most back and neck pain improves, and the strongest evidence supports staying active, which is the opposite of what feels right in the first few days. Know the red flags: loss of bladder or bowel control, numbness in the groin or inner thighs, or weakness or numbness in both legs means an emergency department now, because cauda equina syndrome causes permanent damage if it is not decompressed quickly. Weakness in a leg or arm that is getting worse needs urgent medical assessment. Fever, unexplained weight loss, a history of cancer, significant trauma or new pain over 50 also change what needs to happen. Absent those, imaging early usually does more harm than good, because incidental findings are near-universal and lead to treatment nobody needed.
