I had a spinal fusion, t-5 to t-11 in 2002. Total failure. pain was as abd and got worse than before the operation.
now that my spine is fused and i have already been operated on no one will touch me. many Docs won't even talk to me. I can under stand theres no surgical option due to the fusion area one big bone. but obviously the operation missed the real cause, and it's still there.
but none of that means anything.
you should get a second opinon. maybe a third. make sure you have exhuasted your non surgical options before you think about surgery. surgeons like surgery. that's to be expected. they also tend to think things should be solved through surgey.
but the one thing you cannot do, is undo a surgery. and you don't know how it's going to turn out untill it's over. go for it too soon and it may make other solution impossible.
I knew the risks. I'd seen more than one doctor about it. I knew what the odds of success were, and i hurt so bad. So I said yes.
and now it's ten years of pain and frustraion later, so believe me when i say make your choice carefully, explore other avenues of treatment. do surgey as a last resort.
No matter how good the odds look, sometimes when you roll the dice, you lose

I wish you all the best, and a complete and speedy recovery if you choose sugery. I do realize there may be no other choice for you but surgery.
But like the old knight said in indiana jones 3, "choose wisely."
