I recently had pain in my back that radiated down the left side, hip and leg, to the knee. I was "stuck" in a certain position for about a week. My doc diagnosed sciatica and scheduled an MRI. The MRI shows a bulging disk on the right side but no problems on the left. My doc said that the bulging disk on the right side is not causing the pain on the left side. I took prednisone and it helped a lot but I still pain in the lower back, but my doc doesn't want to treat or send me to a specialist because there is no "known" cause of the pain on the left side. Has anyone else ever had this happen, the pain on the opposite side of a bulging disk? Thank you, any help is very much appreciated.
