Back pain is very common, but its exact cause is often unclear. In most cases it's not caused by anything serious and gets better over time.
Back pain can be felt anywhere along your back. It's most common to have pain in your lower back.
You can usually treat back pain at home with gentle exercises and painkillers. See a GP if it does not get better after a few weeks.
Back pain can sometimes be caused by a problem with the joints, bones or tissues around the spine. But often there's no obvious cause.
