Your back problems sound just like mine! Unfortunately I'm 82! I see a new neurosurgeon next week, the last orthopedic surgeon said my bones are too porous to attach screws. He said he would need to remove all metal from my three lumbar surgeries, replace with new metal and fuse the vertebrae above and below....big surgery for an old lady! I read about a new pain medication the FDA just approved, so I hope it gets produced quickly and is approved by Medicare. It's very frustrating to be in general good health but so incapacitated by my back pain. 😞
