Sciatica is a common condition that causes pain to travel along the sciatic nerve. This nerve runs from your lower back, through your hips and buttocks, down each leg. When your sciatic nerve is irritated or compressed, it can cause sharp, burning, or aching pain. The pain may come and go, sometimes disappearing for weeks or months, only to return suddenly. This cycle can be frustrating and confusing, especially when you wonder, “Why does my sciatica flare up?”
At Direct Orthopedic Therapy, we help patients understand the reasons behind sciatica flare-ups and guide them toward lasting relief. This article explains what causes sciatica flare-ups, how to manage them, and what you can do to prevent future pain.
What Is Sciatica?
Sciatica is not a disease but a symptom of an underlying issue affecting the sciatic nerve. The sciatic nerve is the longest nerve in your body. It starts at your lower spine and travels down your legs. When this nerve is compressed or irritated, it causes pain, numbness, or weakness in your leg.
You may feel different types of pain, such as:
- Sharp or burning sensations
- Aching or throbbing
- Tingling or numbness
- Muscle weakness
Pain is usually felt on one side of the body, but it can affect different parts depending on where the nerve is compressed.
Why Does Sciatica Flare Up?
Sciatica flare-ups happen when something increases pressure or inflammation around the sciatic nerve. Common triggers can range from lifestyle factors to specific health conditions.
Prolonged sitting is one of the most frequent causes. Sitting for hours, especially with poor posture, puts pressure on your lower back and the nerve roots, causing irritation. Similarly, heavy lifting or sudden twisting motions can strain your back, leading to flare-ups.
Another reason is lack of movement. When you are inactive, your muscles can become tight and joints stiff, increasing pressure on the nerve. Poor posture while sitting or standing adds stress to your spine, contributing to nerve irritation.
Even stress and muscle tension play a role. When stressed, your muscles tighten, which can pinch or irritate the nerve. Weight gain also increases the load on your spine and nerves, making flare-ups more likely.
Finally, sudden movements like quick bending or awkward positions may trigger sharp flare-ups.
Underlying Causes of Sciatica Flare-Ups
While triggers worsen symptoms, the root causes involve structural problems in your spine or muscles. These include:
- Herniated discs: When the soft center of a spinal disc pushes through its outer layer and presses on the nerve.
- Spinal stenosis: Narrowing of the spinal canal compresses the nerves.
- Degenerative disc disease: Aging causes discs to wear down and inflame nearby nerves.
- Piriformis syndrome: Tightness or spasms in the piriformis muscle irritate the sciatic nerve.
- Spondylolisthesis: A vertebra slips forward, pressing on nerves.
Each of these conditions can cause nerve compression or irritation, leading to pain that flares up under certain conditions.
How Long Do Sciatica Flare-Ups Last?
Sciatica flare-ups vary in length. Some last a few days, while others may continue for weeks. The severity and duration depend on the cause, your overall health, and how you manage the pain.
Without treatment, flare-ups can become more frequent and last longer. Early intervention and proper care can shorten flare-ups and improve your quality of life.
Managing Sciatica Flare-Ups at Home
When your sciatica flares up, you can take several steps to ease your pain:
Apply heat or cold therapy to relax muscles or reduce inflammation, depending on what feels best. Stay active but avoid prolonged sitting or bed rest. Gentle walking and stretching can help keep your muscles loose. Be mindful of your posture and avoid heavy lifting or sudden twisting.
Remember, these measures help with short-term relief but are not a substitute for professional care.
