Overview
Lower back pain is one of the most common reasons people see a clinician, and most episodes are not caused by anything dangerous. The pain usually comes from the muscles, ligaments and joints around the lower spine adapting to load.
The most useful questions are not "what is damaged?" but "what is aggravating it, and what can be adjusted?" Most back pain improves with sensible activity and time, even when it is intense at first.
What This Symptom Feels Like
- Aching or stiffness in the lower back
- Pain that is worse with bending, lifting or prolonged sitting
- Muscle spasm or tightness
- Pain that eases with movement once it settles
- Sometimes pain that travels into the buttock or leg
Common Causes
- Low back strain — after lifting, twisting or awkward movement
- Lumbar disc herniation with sciatica — back pain plus leg pain in a nerve pattern
- Lumbar spinal stenosis — leg symptoms with walking, more common with age
- Lumbar facet joint pain
- Sacroiliac joint dysfunction
- Spondylolysis and spondylolisthesis
- Piriformis syndrome — deep buttock pain that is worse with sitting
- General load-related back pain without a specific tissue diagnosis
Anatomy Usually Involved
- Lumbar spine — the lower vertebrae, discs and joints
- Intervertebral discs — cushions between the vertebrae
Questions to Ask Yourself
- Did the pain start after a specific lift, twist or event?
- Is it worse with sitting, bending, standing or walking?
- Does it travel into the buttock or leg?
- Is there numbness, tingling or weakness in the legs?
- Any changes in bladder or bowel function?
- Is it improving, staying the same, or getting worse?
When It's Usually Minor
Most back pain, even when severe, is not dangerous and improves over days to weeks. Pain that follows a known physical cause and settles with activity adjustment is the typical pattern.
When To Seek Medical Care
- Saddle numbness, difficulty urinating or loss of bladder or bowel control — urgent
- Weakness developing in both legs — urgent
- Leg numbness or weakness that is progressive
- Pain after major trauma, or pain that is severe and getting worse
- Back pain with fever, chills or unexplained weight loss
- Pain that is not improving after a few weeks
Self-Care Options
- Keep moving within comfort — complete rest is not recommended
- Return to normal activity as soon as reasonably comfortable
- Use short-term pain relief if appropriate for you
- Apply heat for muscle spasm
- Progress trunk and leg strengthening as the pain settles
- Avoid prolonged bed rest, which makes recovery slower
Common Questions
Should I rest with lower back pain?
No. Brief rest during severe flare-ups is fine, but bed rest for days makes recovery slower. Staying active within comfort is the recommended approach.
Does back pain mean I've damaged my spine?
Not usually. Most back pain comes from the muscles, ligaments and joints adapting to load, and it improves with sensible activity — even when it feels intense.
How long does lower back pain last?
Most episodes improve within days to weeks. Some people have pain that comes and goes over months, which is normal and does not mean something was missed.
