Sciatica. It’s one of those terms that’s often thrown around by patients, especially after a quick search online. Many will say they’re dealing with sciatic nerve irritation, but after a thorough assessment, we often find the issue isn’t as straightforward as they might think. Over the years, I’ve learned that sciatica can have a lot more layers to it, and there’s so much more we can do to support these patients than simply focusing on the nerve itself. In this blog, I’ll walk you through how we approach sciatic nerve pain and share some techniques that have helped us achieve better outcomes for my patients. Let’s dive in!

Sciatica can often stem from deeper issues within the body, particularly in the abdominal and pelvic regions. Over the years, we’ve come to understand that visceral manipulation (an approach developed by Jean-Pierre Barral) can have a significant impact on sciatica relief.

Left-Sided Sciatic Pain:Sigmoid and Liver

Left-sided sciatic issues are common in patients with dysfunction in the sigmoid colon or liver. Why? These organs are closely tied to the portal vein drainage system. If there's tension in these areas, the sciatic nerve can become affected.

Issues in this area can also tell us the body is dealing with some level of dysfunction, possibly related to bowel movements, toxins, or nutrition. While this is outside our scope as a physical therapist, it’s an essential clue for knowing when to refer the patient to a nutritionist or other healthcare provider.

Lower Pelvic Organ Tension: Cecum and IC Valve

The cecum (part of the colon) can also contribute to sciatica, especially if there’s gut inflammation. We’ve even seen this area respond to COVID-19, which can cause lasting gut issues.

The Kidney Connection

Another important player in lower back and pelvic issues is the left kidney, especially in cases of pelvic congestion. We often check for any dysfunction in the kidney area, as it can contribute to sciatic-like symptoms.

Working directly on the sciatic nerve (via neural manipulation) itself can have a dramatic effect. One of the most powerful techniques used is to balance the pressure system inside and around the nerve. This can help the surrounding muscles relax and create immediate pain relief.

Sciatic pain isn’t just about nerves and muscles. Vascular health also plays a significant role. We routinely check the pulse on both legs and if the pulse on the affected leg is weak or inconsistent, I address the vascular system to improve blood flow and circulation.

Here’s a real-world example that highlights how sciatica can be misdiagnosed or overlooked. We recently worked with a patient who had left knee pain that would radiate into her hip. After imaging, her doctor recommended a knee replacement, as the knee appeared to be severely worn. Despite going through pre-surgery physical therapy, she still experienced the same pain post-surgery, nine months later.

Upon further assessment, we found that her pain was actually originating from her left sacral plexus, not her knee. After working on the sciatic nerve pathway, sacral dura, and areas like the liver and sigmoid, she could bend and extend her knee without pain by the end of the session!

While the knee replacement may still have been necessary, the source of her pain was not purely structural—it was related to nerve tension and visceral issues.

As part of a holistic approach, we also provide patients with lifestyle changes to help manage their symptoms at home. Here are some helpful tips:

Sciatica is rarely a one-dimensional issue. By considering not only the nerve but also the surrounding muscles, joints, and visceral health, we can provide more comprehensive care to our patients. Using techniques like visceral manipulation, neural manipulation, and visceral-vascular manipulation has helped me treat sciatica more effectively over the years. Every patient is unique, so it's essential to take a holistic approach and tailor treatments to the individual.
