Work accident/ Yeh had an MRI, showed torn Disc L5/S1 & problem with surrounding facets. No nerve impingment, just irritated. Im in CONSTANT pain in mid & lower back, into buttock and ito and down mainly right leg, sometimes, left too. I sometimes get cold and pin & needles in feet. They started me on co-codamol & diclofanac, then to tramadol and diclofenac, then added norotriplyene.
