Quick Answer Sciatica after a car accident is caused by a herniated disc compressing the sciatic nerve root in the lumbar spine. Symptoms include shooting pain down the leg, numbness, and weakness. Diagnosis requires lumbar MRI and NCV/EMG testing. MAIC provides both on-site with same-day scheduling. Call (888) 991-5290.

What Causes Sciatica After a Car Accident

Sciatica occurs when the sciatic nerve — the longest nerve in the body, running from the lower lumbar spine through the buttock and down the leg — is compressed or irritated. Following a car accident, the most common cause is a lumbar disc herniation at L4-L5 or L5-S1 that compresses the nerve root contributing to the sciatic nerve.

Symptoms of Post-Accident Sciatica

  • Sharp, shooting, or burning pain that radiates from the low back through the buttock and down the leg
  • Numbness or tingling in the thigh, leg, or foot
  • Weakness in the leg or foot (foot drop is a serious sign requiring urgent evaluation)
  • Pain that worsens with sitting, coughing, or sneezing
  • Pain that often affects only one side

Diagnosis at MAIC

MAIC's evaluation of post-accident sciatica includes lumbar MRI to confirm disc herniation and identify the specific nerve root compression level; NCV/EMG studies to provide electrophysiological confirmation of the nerve root dysfunction; and orthopedic and pain management evaluation for treatment planning.
