Overview
What Is Lower Back Pain?
Lower back pain is discomfort anywhere between the bottom of the ribs and the top of the hips. It can feel like an ache, stiffness, or a sharp twinge, and it often changes with how you move, sit, or sleep.
It is one of the most common health complaints in the world. Most adults will experience it at some point in life, and it is a leading reason people miss work or visit a doctor.
Everyday things often set it off — sitting for long stretches, lifting something awkwardly, sleeping in an odd position, or slowly getting weaker in the core and hips over time.
Acute pain comes on suddenly and usually improves within a few days to a few weeks. Chronic pain lasts longer than 3 months and often needs a consistent movement plan, not just rest.
The good news: for most people, gentle daily movement, better posture habits, and simple stretches can help reduce discomfort and prevent flare-ups.

Not Sure What's Causing Your Pain?
Symptoms from muscle strain, disc issues, nerve irritation, and joint problems often overlap. Our AI assessment asks a short set of questions about where you feel pain, how it moves with you, what makes it better or worse, and your history — then gives you personalized educational guidance and a stretch routine to try. It is not a medical diagnosis.

Stretches That May Help
Self-Care
Daily Habits That Help
Stay Active
Gentle movement beats bed rest for most low back pain.
Avoid Prolonged Sitting
Break up sitting every 30–45 minutes with a quick stand or walk.
Walk Regularly
A daily 10–20 minute walk keeps the spine loose and blood moving.
Lift Properly
Hinge at the hips, keep the load close, and let your legs do the work.
Improve Posture
Stack ears over shoulders and shoulders over hips when standing or sitting.
Sleep Supported
Try a pillow between or under your knees to unload the low back.
Home Care

When heat may help
