I am 75, female, in good health, I have some scoliosis , and degeneration of the discs and a breakdown of the spine at T12/L1 and L4/L5. This has been causing me quite a lot of pain in my low back and left hip area for 1 1/2 years. I had physical therapy a year ago which helped very little. I am quite active and hate the restrictions this is causing. The doctor says he can do minimally invasive fusion surgery . So many people do everthing they can to avoid surgery. What is the advantage in waiting? I feel that eventually it will have to be done anyway. Right or Wrong?
