Degenerative or age-related changes in our bodies can lead to compression of the nerves (pressure on the nerves that may cause pain and/or damage). Lumbar spinal stenosis is a gradual narrowing of the space where nerves pass through the spine. It may be a result of aging and “wear and tear” on the spine from everyday activities (i.e., degenerative disk disease) and/or resultant positional changes of the vertebrae.
Diagnosing Lumbar Spinal Stenosis:
Your doctor will perform a physical examination to identify areas of pain and weakness and will evaluate your balance and the overall movement of your spine. Your doctor will also collect information about the history of your symptoms, including medicine you have taken for your condition. After your examination, your doctor may use tests to help establish his or her diagnosis. Some of these tests include X-ray, CT (computed tomography) scan and MRI (magnetic resonance imaging). Together, all of these techniques help to confirm a diagnosis of lumbar spinal stenosis.
Symptoms of lumbar spinal stenosis:
- Decreased endurance during physical exercise and activities
- Weakness and/or loss of balance
- Numbness and a “prickly” feeling in your legs, calves, or buttocks
- Aching, dull back pain radiating (spreading) to your legs
- Symptoms improve when you sit, lean forward, lie on your back, or sit with your feet raised
- Neurogenic claudication
