Sciatica is a common source of low back and leg pain. It can feel sharp, burning, or like a deep ache that travels down the leg. For some people, it comes and goes. For others, it lingers and becomes more persistent.
So, what causes sciatica in the first place?
If you’ve been dealing with symptoms that keep returning, it’s natural to want a clear answer. Understanding the cause is the first step toward finding real relief.
What Is Sciatica, Really?
Sciatica is not a condition on its own. Instead, it refers to irritation of the sciatic nerve.
This nerve runs from your lower back, through your hips, and down each leg. When something irritates or puts pressure on the nerve, symptoms can travel along its pathway.
That’s why the pain is often felt in the leg, even though the problem starts in the lower back.
What Causes Sciatica? Common Underlying Issues
There are several reasons why sciatica can develop. In many cases, it’s not just one issue, but a combination of factors building over time.
- Disc Irritation or Bulging. The discs in your spine act as cushions between the bones. When a disc becomes irritated or bulges, it can place pressure on nearby nerves. This is one of the more common answers to what causes sciatica. However, not every case involves a disc issue.
- Joint Restriction in the Spine. Your spine is made up of many small joints that need to move properly. When one of these joints becomes restricted, it can affect how the surrounding area functions. As a result, nearby muscles may tighten, and the nerve may become irritated.
- Muscle Tightness and Imbalance. Muscles in the lower back, hips, and glutes play a big role in supporting movement. If certain muscles become too tight or others become too weak, it can change how your body moves. Over time, this imbalance can place stress on the sciatic nerve.
- Prolonged Sitting. Sitting for long periods can place extra pressure on the lower back and hips. Over time, this can reduce mobility and contribute to irritation in the area. Many people notice their symptoms feel worse after sitting for extended periods.
- Repetitive Strain or Lifting. Repetitive bending, twisting, or lifting can also contribute to sciatica. These movements, especially when done without proper support or recovery, can increase stress on the lower back.
Why Sciatica Develops Over Time
Sciatica usually doesn’t appear suddenly. Instead, it tends to build gradually.
Small stresses add up. Eventually, the body reaches a point where symptoms begin to show.
This is often why people are unsure what causes sciatica in their case. The underlying issue may have been developing for some time.
What Causes Sciatica That Won’t Go Away?
When sciatica lingers, it usually means the root cause hasn’t been fully addressed.
Temporary relief is possible. However, if the underlying issue remains, symptoms often return.
Understanding what causes sciatica in these cases is key. Without that clarity, it’s easy to manage symptoms without actually resolving the problem.
How Chiropractic Care Fits In
Chiropractic care focuses on improving the alignment and movement of your spine with the intent on improving the function of your nervous system.
When movement improves, pressure on the surrounding nerves can decrease. As a result, the irritation that contributes to sciatica may begin to settle.
At our Edmonton clinic, we take the time to assess each person carefully. Then, we create a plan that addresses the underlying cause – not just the symptoms.
