Information for Consumers - Low Back Pain (Acute)
This article tells you about acute low back pain and how it is diagnosed, including what imaging tests you may need to have.
What is acute low back pain?
Acute low back pain usually lasts for a few days to a few weeks. The pain in your lower back may range from an ache to a shooting pain down your leg. If your low back pain has lasted for more than 3 months, it is called chronic back pain.
Acute back pain is very common and in most people will usually go away in a few days. It does not normally need an x-ray or scan for diagnosis.
Your doctor may request x-rays or a scan if:
- He/she thinks that something serious is causing your pain
- If you have other symptoms due to compression of a nerve or the spinal cord
- If your pain lasts several weeks and is not responding to treatment
The following are considered the red alerts for back pain:
- Unexplained weight loss
- History of cancer
- Intravenous drug use
- Osteoporosis or steroid use
- Suspicion of ankylosing spondylitis
- Age >70
- Recent significant trauma or milder trauma in age >50
- Compromised immune system
- Compensation issues
Depending on these, your doctor may request an x-ray, CT, MRI or bone scan.
If an x-ray is done first, the x-ray results will show your doctor whether you need any other scans and which ones you should have.
A Radiology doctor will look at your scans and write a report for your doctor.
