DANGER SIGNS AND BACK PAIN
Both you and your doctor may be worried that something serious is causing your low back pain. Could your pain be caused by cancer or infection in your spine? How does your doctor know for sure?
You will likely need an MRI right away if you have warning signs of a more serious cause of back pain:

Pregnant women should not have MRI scans.
