Sciatica: True sciatica is leg pain that shoots from back, down the leg past the knee. This mimics the path of the sciatic nerve, thus it's name. Mri of the spine or pelvis would serve to differentiate in most cases if exam and history is not clear. Young patients more likely to have herniated disc. Older patients, pressure from arthritic spurs. All can be treated non-surgically if not getting worse.

Pinched nerve: You may have a pinched nerve from one of your herniated discs. You may benefit from rehabilitation and possibly epidural steroid injection to come down the inflammation. You should be evaluated by a physician to determine if there is any nerve damage.
