How to Get Rid of Lower Back Pain — Causes, Treatments, and When to See a Doctor
Lower back pain affects hundreds of millions of people worldwide and is the leading cause of disability globally. Whether your pain is sharp and sudden or dull and long-lasting, this article explains what causes it, what you can do at home, and what medical options are available — all in plain, easy-to-understand language.

Lower Back Pain by the Numbers
Understanding how widespread this condition is can be reassuring — you are not alone, and effective treatments do exist.
What Causes Lower Back Pain?
Lower back pain rarely has a single cause. Most cases are what doctors call "non-specific" — meaning no single damaged structure can be pinpointed on a scan. However, several well-known factors drive the condition.
Common Causes
Muscle or Ligament Strain
Lifting heavy objects awkwardly, sudden movements, or sleeping in a bad position can strain the muscles and ligaments that support your spine.
Disc Problems
The soft discs between your spinal bones can bulge or rupture (herniated disc) and press on nearby nerves, causing sharp or shooting pain down the leg (sciatica).
Arthritis and Bone Changes
Osteoarthritis can narrow the spaces in the spine (spinal stenosis), causing pain, weakness, and numbness — especially in older adults.
Poor Posture and Sitting
Long hours at a desk, hunching over a phone, or working in physically demanding jobs increases pressure on the lower spine significantly over time.
Excess Body Weight
Carrying extra weight — particularly around the abdomen — shifts your center of gravity forward and places abnormal stress on your lumbar (lower) spine.
Psychological Stress
Anxiety and depression are strongly linked to chronic back pain. Stress tightens muscles and alters how the brain processes pain signals, making pain feel more intense.
According to a global burden of disease analysis, occupational hazards, smoking, and high body mass index together account for approximately 38 to 40 percent of all disability caused by lower back pain worldwide.

Symptoms — What Lower Back Pain Feels Like
Back pain can take many different forms. Knowing your type of pain helps a doctor find the right treatment faster.
- Dull, aching pain — the most common type, felt deep in the lower back, often worsening after sitting or standing for long periods
- Sharp, stabbing pain — usually caused by a muscle spasm or a compressed nerve, and can be triggered by movement
- Pain that radiates down the leg — known as sciatica, caused by a disc pressing on the sciatic nerve; can feel like a burning or electric shock sensation
- Stiffness in the morning — common in people with arthritis or ankylosing spondylitis; usually improves after gentle movement
- Pain that comes and goes — may indicate a recurring muscle strain or stress-related tension in the back muscles
- Numbness or tingling — a sign that a nerve may be compressed; should always be evaluated by a healthcare professional
Home Remedies for Lower Back Pain
For most people with mild to moderate back pain, simple self-care steps at home provide real relief within a few days to a few weeks. These are the approaches backed by the strongest evidence.
First Line: Self-Care
Stay Active
Bed rest is no longer recommended. Gentle walking and normal daily activity prevent muscles from weakening and help the back recover faster.
Apply Heat
A heat pad or warm compress applied to the lower back for 15 to 20 minutes provides moderate evidence-backed relief for short-term back pain. Avoid heat on inflamed or swollen areas.
Stretch and Exercise
Gentle stretches — such as knee-to-chest pulls, cat-cow movements, and hip flexor stretches — release tension. Supervised exercise programs have moderate evidence for chronic back pain.
Check Your Posture
Sit with your feet flat on the floor, keep your computer screen at eye level, and take a short standing break every 30 to 45 minutes if you work at a desk.
Manage Stress
Mindfulness meditation, deep breathing, and cognitive behavioral therapy (CBT) have strong evidence for reducing chronic back pain — especially when combined with physical therapy.
Improve Sleep Position
Sleep on your side with a pillow between your knees, or on your back with a pillow under your knees, to keep the spine in a neutral position and reduce overnight pressure.
Medical Treatments for Lower Back Pain
When home care is not enough, several medical treatments are available — ranging from over-the-counter medications to specialist procedures.
| Treatment | Type | Evidence | Notes |
|---|---|---|---|
| NSAIDs (ibuprofen, naproxen) | Medication | Strong | First-line drug option per ACP and NICE guidelines; use lowest dose for shortest time |
| Duloxetine (Cymbalta) | Medication | Strong | Recommended for chronic lower back pain when NSAIDs are insufficient; an SNRI antidepressant |
| Physical Therapy | Rehabilitation | Strong | Structured exercise with a physiotherapist; especially effective for long-term management |
| Cognitive Behavioral Therapy | Psychological | Strong | Significant pain and disability reduction when combined with physical therapy in clinical trials |
| Acupuncture | Alternative | Moderate | Cochrane review: possibly relieves pain versus no treatment; low-certainty vs. sham acupuncture |
| Epidural Steroid Injections | Interventional | Moderate | Short-term relief for nerve-related back pain; effect typically lasts weeks to months |
| Radiofrequency Denervation | Interventional | Moderate | NICE recommends considering this after non-surgical treatments fail and pain is 5 or above on a 10-point scale |
| Opioid Pain Medications | Medication | Reserve | Only after all first and second-line options have failed; risks must outweigh benefits; not a first choice |
| Spinal Surgery (Fusion) | Surgical | Selective | NICE advises against routine spinal fusion for non-specific back pain; reserved for specific structural conditions |

When to See a Doctor Immediately
Most back pain improves with self-care within 4 to 6 weeks. However, certain symptoms require urgent medical attention. Go to an emergency department or call your doctor right away if you experience any of the following:
- Pain following a serious fall, accident, or direct impact to the spine
- Loss of bladder or bowel control — this may signal a medical emergency called cauda equina syndrome
- Progressive numbness, tingling, or weakness in one or both legs
- Back pain accompanied by unexplained fever, chills, or night sweats
- Pain that does not improve after 6 weeks of home treatment and rest
- Back pain in a person with a history of cancer, osteoporosis, or long-term steroid use
- Severe, constant pain that is worse at night and not relieved by any position
- Unintended weight loss alongside ongoing back pain
How to Prevent Lower Back Pain Coming Back
Once your back feels better, the goal shifts to keeping it that way. Prevention is largely about building habits that support your spine every day.
- Build core strength — exercises targeting the deep abdominal and back muscles (such as planks and bird-dogs) act like a natural brace for your spine
- Maintain a healthy weight — losing even 5 to 10 percent of body weight reduces lumbar load significantly
- Quit smoking — smokers have higher rates of back pain because nicotine restricts blood flow to spinal discs and speeds up their degeneration
- Lift correctly — bend at the knees, keep the object close to your body, and never twist while lifting
- Ergonomic workstation — invest in a supportive chair with lumbar support, position your screen at eye level, and keep your keyboard at elbow height
- Stay physically active — regular moderate exercise such as swimming, walking, or yoga keeps muscles flexible and the spine well-supported
Key Takeaways
- Lower back pain affects over 619 million people globally and is the world's leading cause of disability
- Most acute (short-term) back pain improves with staying active, applying heat, and gentle stretching within 4 to 6 weeks
- NSAIDs, physical therapy, and cognitive behavioral therapy are the strongest evidence-based treatments
- Avoid prolonged bed rest — gentle movement is almost always better for recovery
- Opioids and surgery are reserved for specific cases and should not be the first treatment tried
- Seek emergency care if you have leg weakness, bladder or bowel changes, or pain after major trauma
- Long-term prevention comes from core strength, healthy weight, quitting smoking, and good posture habits
