Hi all
I'm a newbie from Brisbane in Australia. I have issues with my two lowest discs. I have pain across lower back . I cannot run anymore and walking is difficult at times. I am 50 with two young children. I have been told fusion at L 5/S1 and disc replacement above. My questions are will I be able to return to a healthy life running , cycling and how long after surgery would this be expected if at all
