Spinal stenosis

Spinal stenosis

• Pain in the buttocks, thighs or calves that is worse with walking or exercise
• Numbness in the buttocks, thighs or calves, that is worse with standing, walking or exercise
• Back pain that radiates to the legs
• Weakness of the legs
• Neck pain
• Leg pain
• Difficulty or imbalance when walking

An examination of reflexes of lower legs reveals asymmetry. Neurologic examination confirms leg weakness and decreased sensation in the legs.

• X-ray of the spine shows degenerative changes and narrowed spinal canal.
• Spinal MRI or spinal CT scan shows spinal stenosis.
• EMG may show active and chronic neurological changes.
