10 Causes of Sciatic Nerve Pain
Reviewed: Dr. Gromatzky
Cause #9: Piriformis Syndrome
Piriformis syndrome is a condition which has been estimated to contribute to 8 percent of lower back pain. In some individuals, the sciatic nerve goes through the piriformis muscle instead of under it. This means that when there is spasm in the piriformis muscle due to overuse or trauma, this can compress the sciatic nerve leading to pain and limited movement.
It can be suspected as a cause of sciatica when there is no spinal disc herniation or when the spinal nerve roots appear to be normal.
