What muscle is known to potentially impinge on the sciatic nerve?

The piriformis muscle is known to potentially impinge on the sciatic nerve due to its anatomical relationship with the nerve. The sciatic nerve runs close to the piriformis muscle as it exits the pelvis. In some individuals, the sciatic nerve may even pass through the muscle itself. When the piriformis muscle becomes tight or spasms, it can exert pressure on the sciatic nerve, leading to symptoms such as pain, tingling, or numbness along the path of the nerve down the leg, a condition often referred to as piriformis syndrome. Understanding this relationship is crucial for sports massage practitioners, as it influences the techniques used in addressing lower back and leg pain associated with sciatic nerve irritation.
