Betsy, don't take just ONE Neuro's opinion, okay? You've GOT to have at least 3 opinions before you opt for surgery! As you know, this is a life changing event!
And you may have just been lucky the first time around, because surgery is NOT for pain. Surgery is only for mechanical problems. usually you're left with the same pain or worse! And not only that, but you have to figure on the "Domino Effect" where the levels above/below the surgery site fail. This happens all the time.
So make sure you get more than one opinion, okay? Hugs, Lee
