A New Episode of Low Back Pain: What Usually Happens, and What Should Make You Call
Eight in ten people have back pain at some point. Most episodes settle in days to weeks — and a few signs mean you should not wait.

You bent to lift something ordinary and felt it go. Or you woke up and simply could not straighten. A new episode of low back pain is alarming out of proportion to how common it is — and it is very common. NIH figures cited by MedlinePlus put it at about eight in ten people at some point in their lives.
The usual course
Back pain ranges from a dull constant ache to a sudden sharp pain. Acute back pain comes on suddenly and usually lasts from a few days to a few weeks. Pain is called chronic when it lasts more than three months. Most back pain goes away on its own, though it may take a while — a sentence worth holding on to in the first miserable days.
What helps early — and what no longer is advised
Over-the-counter pain relievers used as directed, heat or cold packs, and a short period of taking it easy can help. The advice that has changed most over the years concerns rest: staying in bed for more than one or two days can make back pain worse. Gradually returning to walking and normal activities, pacing tasks rather than doing everything on a good day, and paying attention to posture at desks and screens are the practical measures most people start with.
When to call
If the pain is severe or does not improve after three days, call your health care provider. Get medical attention if back pain follows an injury. And seek emergency care for back pain with loss of bladder or bowel control, numbness in the groin or inner thighs, or new weakness in the legs — these can indicate pressure on the nerves at the base of the spine and are not to be waited out.
If it keeps going
Treatment depends on the type of pain and what is causing it, and may include hot or cold packs, exercise, medicines, injections, complementary treatments and, sometimes, surgery. When pain persists, spreads down a leg (sciatica — a symptom of a problem with the sciatic nerve, often from a ruptured disc or narrowing of the spinal canal), or keeps returning, a specialist assessment helps work out which structure is responsible. SEVA Healthcare lists the following for back and neck pain on its official page: epidural steroid injections, facet joint injections, radiofrequency ablation, spinal cord stimulation, interspinous decompression and kyphoplasty. These are image-guided procedures aimed at specific sources of pain and are not needed for most episodes; whether any is appropriate depends on an evaluation.
Questions to discuss with your clinician
- What do you think is causing my pain, and do I need imaging? (Imaging is not needed for most episodes.)
- Which activities should I continue, and which should I avoid for now?
- What signs mean I should come back sooner or go to the emergency department?
- If a procedure is suggested, what is it meant to do, how long does relief usually last, and what are the alternatives?
