How is piriformis syndrome diagnosed?
Your doctor will perform a physical exam. He or she will move the affected leg into several different positions to check your pain level.
If your doctor thinks something other than piriformis syndrome is causing your sciatica, he or she may order additional tests. Computerized tomography (CT) and magnetic resonance imaging (MRI) scans cannot diagnose piriformis syndrome, but they may show your doctor if something else is pressing on your sciatic nerve.
