Sciatica vs. Piriformis Syndrome: What’s the Difference?
Pain that starts in the lower back or buttock and travels down the leg is often called “sciatica.” But not every case of pain along the sciatic nerve starts in the spine. Piriformis syndrome can cause very similar symptoms, which is why the two conditions are sometimes confused.
Understanding where the irritation begins can help determine what may be causing your symptoms and what type of care may be appropriate.
What Is Sciatica?
Sciatica refers to symptoms caused by irritation or compression of the sciatic nerve, most commonly involving one of the nerve roots in the lower spine.
The pain may begin in the lower back or buttock and travel into the thigh, calf, or foot. It can feel sharp, burning, aching, or even like an electric shock. Some people also experience tingling, numbness, or weakness in the affected leg.
A herniated disc, spinal stenosis, or age-related changes in the spine are among the conditions that can irritate the nerve roots and cause sciatica.
What Is Piriformis Syndrome?
The piriformis is a small muscle located deep in the buttock that helps control movement of the hip. The sciatic nerve usually passes beneath this muscle.
With piriformis syndrome, the sciatic nerve becomes irritated or compressed near the piriformis muscle rather than at the lower spine. This can cause pain, tingling, or numbness in the buttock that may travel down the back of the leg.
Symptoms are often aggravated by prolonged sitting or certain movements involving the hip.
How Can You Tell the Difference?
The biggest difference is where the sciatic nerve is being irritated. With sciatica originating from the spine, irritation occurs around the nerve roots in the lower back. With piriformis syndrome, the irritation occurs farther down, in the buttock.
However, symptoms can overlap considerably. Both can cause buttock and leg pain, and where you feel the pain doesn’t always tell you exactly where the problem originates.
That’s why an evaluation can be important. Your health history, the location and pattern of your symptoms, muscle strength, reflexes, sensation, and how your lower back and hips move can all provide clues about the source of the problem.
Why Does the Difference Matter?
Similar symptoms don’t necessarily mean the same underlying problem. Identifying where the irritation is coming from can help guide the most appropriate approach to care.
