From having witnessed my father over the decades, I would do everything possible to avoid back surgery. He must’ve been in his early 30’s when he had his first operation, which led to another years later, then another, then another, then another, then another, each time thinking the next surgery would cure the problems caused – yes perhaps somewhat by the initial problem, but – mostly by the succession of surgeries. My dad’s always enjoyed exercise, was on his college swim team and hikes regularly, but now almost age 80 his back is rigid from all the discs fused together (5? 6?), fancy metal contraptions imbedded inside, and tensed, tangled knots of muscles and scar tissue where all the incisions were made in failed attempts to cauterized pinched nerves or fix worn out discs, etc., etc., and from the insertions and removals of various devices. And it didn’t all turn bad for him in his 70’s. While he’s enjoyed an active lifestyle since my childhood – waterskiing, climbing mountains, traveling – he’s always known back pain, sometimes subsiding so that others aren’t aware of his condition, but other times getting so excruciating that we all know he’s a mess and is drugging himself heavily trying to deal with the pain.
As I mentioned, having seen his progression over the decades, I strongly believe he screwed up by going under the knife over and over and over. His back has now been messed with by so many surgeons (admittedly many are superstars in the medical profession, but so what) and been altered in so many unnatural ways, that he could never expect to have it return to anything close to a normal, healthy state.
So, good luck to you. Having seen what I’ve seen, I’d do everything possible to lose weight, do gentle stretching exercises regularly (twice a day), begin a very slow, easy light-weight weight-lifting program to strengthen the back muscles, use massage, heating pads, hot-tubs, etc, and forestall surgery until you’re in screaming pain and absolutely can’t take another minute.
