5 Common Causes of Sciatica
Sciatica is one of the most common, yet often misunderstood types of pain.
The pain in sciatica radiates along the path of the sciatic nerve. This nerve runs from your lower back, down to your hips and buttocks and each of your legs.
Normally, only one side of the body is affected by sciatica.
What causes sciatica?
There are different possible causes of sciatica. The most common ones are:
• A herniated disc
We have intervertebral discs in between each vertebrae of our spine. They are considered as our body’s shock absorbers.
The lower back intervertebral discs are particularly important because they support most of our body’s weight when we stand and walk.
When one of these discs protrude into the spinal canal, a condition called herniated disc occurs. This may happen for several reasons, including the natural and gradual aging-related wear and tear.
When the disc herniates, a portion of it may press on the spinal nerve causing the radiating pain we call sciatica.
• Osteoarthritis
Like other joints of our body, the facet joints of our spine are also susceptible to a condition called osteoarthritis. It’s the type of arthritis that results from the wear and tear of joint bone and soft tissue.
When osteoarthritis affects the facet joints of the spine, it may affect the surrounding nerves as well. In some cases, it may give way to the development of bone spurs that can put pressure on the nerve roots.
• Spinal stenosis
Sciatica can be a symptom of spinal stenosis. It’s a condition characterized by the narrowing of the spinal column.
As the spinal column narrows, the vertebrae start to press on the spinal nerve causing the typical symptoms of sciatica – numbness, tingling sensation, and muscle weakness.
• Spondylolisthesis
Spondylolisthesis is a condition that occurs when one of the bones in your spine (called the vertebrae) slips out of its position. The most common cause of it is a fracture brought by a high impact injury.
This condition usually occurs in the lower back (lumbar region) although it can occur in other sections of the spine. When the lumbar vertebrae slips out and protrudes into the spinal canal, it can pinch the spinal cord causing sciatica.
• Muscle spasms
The sciatic nerve and its branches serve many muscles in the back and legs. Having muscle spasms may put pressure on the nerve and/or its branches causing the classic sciatica symptoms.
Sciatica caused by muscle spasms can be easily relieved with nonsurgical intervention. This includes rests, use of anti-inflammatory medications, bracing, and physical therapy.
