Nerve root compressions and radiculopathy

Overview

The Science of Sciatica

Sciatica describes pain along the path, usually from compression or irritation at the spine level. The nerve can be affected by disc material, , or tight muscles along its path. Similar to general low back pain, sciatica often involves disc dysfunction, but with the added complexity of compression or irritation.

When the nerve is irritated, it can cause pain, numbness, or weakness anywhere along its path from the back to the foot. The location and type of symptoms help identify where the problem originates. In some cases, sciatica may occur alongside disc disease or spinal , requiring careful assessment to address all contributing factors. Sciatica rehabilitation centres on identifying the specific source of nerve irritation and applying targeted strategies to reduce compression. Sciatic nerve pain relief is typically achieved through a combination of directional exercises, , and activity modification tailored to the individual presentation.

Prolonged sitting is one of the biggest culprits I see with sciatica. When you sit, especially with poor posture, you increase the pressure on your discs by approximately 30% compared to standing (though the difference is minimal with proper upright posture). This forward-slumped position narrows the spaces where nerves exit your spine, potentially compressing the that form your .

Poor lifting mechanics multiply the problem. When you bend at your waist with a rounded back instead of squatting down, you can increase bending stress on your discs, more so when bending is combined with twisting. Combined with lifting weight away from your body, this creates massive compressive and shearing forces on your lower spine. Repetitive bending, twisting, and lifting - especially first thing in the morning when your discs are most hydrated and vulnerable - sets up the perfect storm for disc problems.

Your movement patterns throughout the day matter tremendously. Tight hip flexors from prolonged sitting pull on your lower back, forcing your lumbar spine into excessive extension. Weak glutes fail to stabilize your pelvis during walking and stair climbing, placing extra demands on your spine. Even something as simple as how you get out of bed or your car can repeatedly stress the exact structures that are already irritated.
