How long does lower back pain last?

The usual timeline

For a new episode of lower back pain with no warning signs, most people notice real improvement within the first few weeks, and many are much better by around six weeks. Some are back to normal within days. Others take longer, especially if the pain was severe at the start or their work is physically demanding.

These are general patterns, not promises. Your own recovery depends on your health, your activity, and what set the pain off.

Acute, sub-acute and persistent pain

• Acute: pain that has lasted up to about six weeks
• Sub-acute: pain lasting roughly six to twelve weeks
• Persistent (chronic): pain lasting longer than about three months

Persistent pain does not mean something is damaged or that it cannot improve. It usually means the back has become sensitive and needs a longer, more gradual plan built on activity and strength.

Why it can take longer

• Staying in bed or avoiding movement for too long, which can stiffen the back
• Fear of making it worse, so you stop doing normal things
• Poor sleep, high stress or low mood, which can turn up pain sensitivity
• Heavy physical work, or returning to full activity too fast
• Having had back pain before

Back pain often comes back. Many people have another episode within a year, which is common and does not mean something new is wrong.

What helps it settle

• Keep moving with short, regular walks and your usual activities, adjusting as needed
• Change position often rather than staying in one posture
• Use heat or simple pain relief as your pharmacist or doctor advises
• Build back up gradually when you return to exercise or work
• Get enough sleep, and tell someone if stress or low mood is getting on top of you

When a physio can help

A physio can confirm what is likely going on, give you exercises that suit your stage of recovery, and help you return to work or sport with a plan. Seeing one early can help you feel confident moving, and seeing one later can help if the pain is lingering or keeps returning. Read more in our physio for back pain guide.

Warning signs to see a doctor first

Get medical help promptly, or go to an emergency department, if you have numbness around the groin or buttocks, trouble controlling your bladder or bowels, a leg that is getting weaker, pain after a significant injury, or fever with back pain. Also see your GP if your pain is steadily getting worse, wakes you at night or is not improving after several weeks.

Pain that goes down the leg

If your pain spreads into your buttock or leg, it may be sciatica, which often has a different recovery pattern. See our sciatica guide for more.
