Pain that starts in your buttock and travels down your leg is often called sciatica, but that is not always the correct diagnosis. Another condition called piriformis syndrome can produce very similar symptoms because it also irritates the sciatic nerve.
The biggest difference is where the problem begins. Sciatica usually starts in the lower spine, where a pinched nerve may be irritated by a herniated disc, arthritis, or another spinal condition. Piriformis syndrome begins in the piriformis muscle deep within the buttock, where muscle tightness or inflammation irritates the sciatic nerve.
Although the symptoms overlap, identifying the true cause is important because the most effective treatment depends on the source of the irritation.

Sciatica refers to irritation of the sciatic nerve, the largest nerve in the body. The sciatic nerve begins in the lower spine, passes through the buttock, and continues down the back of each leg.
Most cases occur because one of the spinal nerve roots becomes irritated before it joins the sciatic nerve. That irritation can cause pain that travels from the lower back into the hip, buttock, leg, or foot.
Common causes include:
Because the problem often begins in the spine, many people also experience back pain along with leg pain.
The piriformis is a small muscle located deep beneath the gluteal muscles. It helps rotate and stabilize the hip during walking, running, and changing direction.
The sciatic nerve travels directly underneath this muscle, and in some people it may even pass through it. When the piriformis muscle becomes tight, inflamed, or irritated, it can place pressure on the sciatic nerve.
This can create pain that feels very similar to sciatica, even though the source is different. Instead of a spinal nerve root being compressed, the irritation is coming from the deep hip and buttock region.

Both conditions may cause:
Because these symptoms overlap, self-diagnosis can be difficult.
Sciatica is more likely if you have:
If leg pain keeps returning or is becoming more intense, it may also contribute to chronic pain if the underlying cause is not addressed.
Piriformis syndrome is more likely if you have:
Because piriformis syndrome involves the hip and buttock region, it may also overlap with symptoms discussed on our hip pain page.
Although both conditions involve irritation of the sciatic nerve, treating the wrong problem can delay recovery. Stretching the piriformis muscle may help someone with piriformis syndrome, but it may not address a lumbar disc problem. Likewise, focusing only on the lower back may not fully resolve symptoms if the piriformis muscle is the primary source of irritation.
This is why an evaluation matters. The goal is not just to name the pain, but to understand why the sciatic nerve is being irritated in the first place.
At Western New York Spine & Chiropractic, your evaluation begins with a detailed examination rather than guessing based on symptoms alone.
Depending on your condition, your chiropractor may assess:
In some cases, additional imaging or referral may be recommended if symptoms suggest a more serious spinal condition.
Treatment depends on the underlying cause.
For spinal-related sciatica, care may include chiropractic adjustments, flexion-distraction therapy, manual therapy, mobility exercises, and posture support.
For piriformis syndrome, treatment often focuses on reducing muscle tension, improving hip mobility, stretching and strengthening, soft tissue therapy, and correcting movement patterns.
The goal is to relieve pressure on the sciatic nerve while addressing the condition causing it.
Schedule an evaluation if:
If you experience sudden loss of bowel or bladder control or rapidly progressing weakness, seek emergency medical care immediately.
Not exactly. Piriformis syndrome can irritate the sciatic nerve and produce sciatica-like symptoms, but the underlying cause is muscular rather than spinal.
Yes. Some patients have both lumbar nerve irritation and tightness of the piriformis muscle, which makes a professional evaluation especially important.
Often it does not. Imaging is more useful for identifying spinal conditions such as herniated discs or spinal stenosis.
Sciatica caused by spinal problems is generally more common than piriformis syndrome.
Pain traveling down your leg does not automatically mean you have sciatica. Likewise, buttock pain is not always caused by the piriformis muscle.
Finding the true source of your symptoms is the first step toward lasting relief.
If you are experiencing persistent leg pain, numbness, or tingling, the team at Western New York Spine & Chiropractic can perform a thorough evaluation to determine what is causing your symptoms and recommend the most appropriate treatment plan.
