The Lumbosacral JointThis pain typically presents when the nerve is inflamed, compressed, or irritated. Numbness or chronic weakness can also happen in the lower extremities and can cause unbearable discomfort. Some of the reasons that make the joint a prime suspect for sciatic pain include:
- The L5 vertebrae are vulnerable to slipping forward over the connecting S1 vertebrae. The sciatic nerve goes through this area, leaving it open to compression.
- A disc herniation and/or inflammation can also stress the sciatic nerves.
- Deterioration of the lumbosacral facet joints is common with older individuals. This can lead to nerve compression and sciatic nerve irritation.
- Piriformis syndrome can affect the area around the lumbosacral joint, causing nerve compression and inflammation.
Other Spinal ConditionsThe lumbosacral joint also experiences problems that stem from chronic conditions, which can involve some form of sciatic pain as a symptom. They include:
- Degenerative disc disease
- Lumbar stenosis
- Sacroiliac joint dysfunction
