Sciatica is caused by irritation or compression of the sciatic nerve, the longest nerve in your body. It runs from your lower back, through your hips and buttocks, and down each leg. When this nerve is irritated or pinched, it can cause pain, numbness, tingling, or weakness along its path—this condition is known as sciatica.
Common Causes of Sciatica:
- Herniated or Slipped Disc
- This is the most common cause. A disc in the spine bulges out and presses on the sciatic nerve.
- Spinal Stenosis
- Narrowing of the spinal canal can compress nerves, including the sciatic nerve.
- Degenerative Disc Disease
- Wear and tear on the spinal discs over time can lead to nerve irritation.
- Spondylolisthesis
- A condition where one vertebra slips forward over the one below it, pinching the nerve.
- Piriformis Syndrome
- The piriformis muscle, located in the buttocks, can sometimes irritate the sciatic nerve if it spasms or becomes tight.
- Injury or Trauma
- Accidents, falls, or direct trauma to the lower back or buttocks can damage or irritate the nerve.
Risk Factors:
● Age (disc degeneration is more likely as you age)
● Obesity (adds stress to the spine)
● Sedentary lifestyle
● Diabetes (can increase risk of nerve damage)
● Jobs that involve heavy lifting, twisting, or prolonged sitting
If you’re experiencing sciatica symptoms, especially if they are severe, last more than a few weeks, or worsen over time, it’s important to see a healthcare provider in Lenoir City for proper diagnosis and treatment.
