How does the doctor diagnose the exact cause of sciatica?
An accurate history is the most important diagnostic tool. The way the pain started and progressed; specific aggravating and relieving factors of pain; distribution of pain over your body, associated complaints such as weakness or numbness over the lower limbs will be a guide to short listing the possible causes of your low back pain and sciatica. A very important history relates to difficulty in controlling or passing urine.
