What Causes Lower Back Pain?
There are many causes of lower back pain. Most of the time, lower back pain is a result of a disruption in the way the parts of the back (the spine, muscles, discs, and nerves) fit together and move.

How Is Lower Back Pain Diagnosed?
The cause of lower back pain is diagnosed with a patient history and physical examination of the back. The physical examination may also include a range of motion tests to check mobility as well as a neurological examination to check muscle strength, skin sensation, reflexes, and cranial nerves.
Additional tests used to diagnose the cause of lower back pain may include:
- Imaging tests
- X-ray
- Magnetic resonance imaging (MRI) scan
- Computerized tomography (CT) scan
- Bone scan
- SPECT scan
- DEXA scan (also called bone densitometry)
- Electrodiagnostic tests
- Nerve conduction studies
- Electromyography (EMG)
- Somatosensory evoked potentials (SSEP) if spinal cord dysfunction is suspected
- Diagnostic injections to help pinpoint specific anatomical structures as the pain source
- Facet joint injection
- Medial branch block
- Selective nerve root block
- Lumbar sympathetic nerve blocks
- Sacroiliac joint blocks
- Stellate ganglion blocks
What Is the Treatment for Lower Back Pain?
It is important to see a doctor for a proper diagnosis of the cause of lower back pain so the proper treatment plan can be implemented.
Home treatment to relieve lower back pain may include:

- Anticonvulsants (may be helpful for sciatica)
- Tricyclics and serotonin and norepinephrine reuptake inhibitor antidepressants (SNRIs)
- Spinal manipulation and spinal mobilization such as chiropractic
- Transcutaneous electrical nerve stimulation (TENS)
