I had a L4 L5 ADR in february of 2009... I am still in excrutiating lower back pain.. One year to the date I developed a numb left foot. if i touch my ankle area i get electric like shocks to the top of my foot...I think it is a nerve problem directly from the surgery area. I am scheduled for a CT scan of my back next week...wondering if anybody else has had their disc move a bit??? or any other complications one whole year after surgery??? I have still not returned to my job as a nurse either due to increased back pain when i am upright for periods of time. any ideas?
