The first step is to determine the cause of the pain.
Sciatic pain will generally extend below the knee and the most common cause are disc herniations at l4-5 or l5-s1. If an MRI
does not reveal a source, there are times that the sciatic nerve can be entraped as it exits the pelvis, piriformis syndrome. The history of onset and examination are key to making the right diagnosis and treatment plan.
