Is Piriformis Syndrome The Same Thing As Sciatica?

If you’ve ever experienced a deep, nagging pain in your buttock that radiates down your leg, chances are someone may have mentioned sciatica. However, not all sciatic pain is created equal. One lesser-known cause of sciatica-like symptoms is piriformis syndrome, a condition that is often confused with true sciatica. Though they may feel similar, piriformis syndrome and sciatica are not the same, and understanding the difference is essential for proper treatment.

What Is Sciatica?

Sciatica refers to pain that follows the path of the sciatic nerve, which is the longest and widest nerve in the body. It runs from the lower spine, through the buttocks, and down the back of each leg. Sciatica is not a diagnosis, but rather a symptom of an underlying issue that irritates or compresses the sciatic nerve.

Most cases of sciatica are caused by spinal conditions such as a herniated disc, degenerative disc disease, spinal stenosis, or spondylolisthesis. These conditions put pressure on the nerve roots in the lumbar spine, triggering pain that can radiate down the leg, often accompanied by tingling, numbness, or muscle weakness. Pain typically starts in the lower back and travels downward.

What Is Piriformis Syndrome?

Piriformis syndrome, on the other hand, originates in a muscle rather than the spine. The piriformis is a small, flat muscle located deep in the buttock, behind the larger gluteus maximus. It is one of six muscles responsible for laterally rotating the hip and plays a role in stabilising the hip joint during walking and movement.

In some individuals, the sciatic nerve passes underneath, or even through, the piriformis muscle. If this muscle becomes tight, inflamed, or injured, it can compress the sciatic nerve, leading to symptoms that closely resemble sciatica. This condition is referred to as piriformis syndrome.

Similar Symptoms, Different Origins

The confusion between piriformis syndrome and sciatica often arises because both conditions involve irritation of the sciatic nerve, producing similar symptoms: pain radiating down the leg, tingling, or a burning sensation. However, their origins are distinctly different.

Sciatica is caused by spinal nerve root compression, whereas piriformis syndrome stems from soft tissue compression of the nerve outside the spinal canal. In piriformis syndrome, the pain is often centred in the buttock and may or may not travel down the leg. Lower back pain is usually absent. People may notice discomfort when sitting for long periods, climbing stairs, or performing hip-related movements.

How Can You Tell Them Apart?

Not all sciatic pain is caused by the spine. In fact, many patients ask, “Is my pain sciatica or something else?” Understanding this distinction is the first step to choosing the right treatment. Differentiating between the two can be difficult, especially since standard imaging like MRIs or X-rays may not show evidence of piriformis syndrome. Sciatica due to spinal conditions often appears on these scans, helping guide diagnosis.

In the case of piriformis syndrome, diagnosis is largely clinical. Practitioners assess movement patterns, posture, and muscle tightness through physical exams. Pain triggered by pressing on the piriformis muscle or performing specific leg movements can indicate muscular involvement rather than spinal compression.

At Flynn Chiro, a thorough history and hands-on assessment help determine whether symptoms stem from spinal structures or muscular dysfunction. A chiropractor in Melbourne can help identify the root cause of sciatic-type pain and create a targeted treatment plan.

What Causes Piriformis Syndrome?

Piriformis syndrome may develop from muscle overuse, trauma, or repetitive motion. It’s common among runners, cyclists, or individuals who sit for extended periods without proper posture. Muscle imbalances, improper biomechanics, or direct injury to the buttocks can also contribute.

The condition may be more common in women than men, possibly due to anatomical differences in pelvic structure and gait. Some research also suggests that women may be more susceptible to muscle spasms in the piriformis due to hormonal and structural factors.

Treatment For Piriformis Syndrome And Sciatica

Though their causes differ, the management of both conditions often begins with conservative treatment. For spinal sciatica, addressing the root cause, whether it be a disc issue or spinal narrowing,is key. Treatments may include spinal adjustments, physiotherapy, core strengthening, and posture correction.

Piriformis syndrome, however, requires a focus on relaxing the piriformis muscle and improving pelvic mobility. Stretching routines, soft tissue therapy, dry needling, and manual release techniques can help relieve muscle tension.

Chiropractic care can be particularly helpful in treating both spinal and muscular sources of sciatic pain. Dr Flynn Petterson, a trusted chiropractor Melbourne patients rely on, explains:

“In my practice, we often see patients with sciatic pain who have had spinal imaging with no findings. In many of those cases, the problem isn’t in the spine at all, it’s the piriformis muscle. With the right assessment, we can address the muscular imbalance and provide real, lasting relief.”

Conclusion

While piriformis syndrome and sciatica can feel nearly identical, they are not the same. The key difference lies in the source of nerve irritation: spinal structures in the case of sciatica, and a small but troublesome muscle in piriformis syndrome. Understanding where your symptoms are coming from is essential for receiving the correct treatment.

If you’re experiencing persistent leg, buttock, or hip pain, don’t assume it’s “just sciatica.” An accurate diagnosis by a trained professional, such as a chiropractor in Melbourne, can make all the difference in getting you on the path to recovery.
