I find it interesting, @michc56, our varying experiences with neurosurgery. When I told friends I as going to see a neurosurgeon, their reaction was typical: "Watch out, Ray. He's a surgeon. You'll be talked into surgery." And yet my experience with the neurosurgeon proved quite the opposite. He mentioned things like falls and paralysis, but something in how he was telling me these things made his delivery seem rather pro forma. What didn't come across as pro forma was his saying the spinal encrochment was "borderline," and that he was reluctant to suggest there might be any urgency when he, privately, didn't believe there was urgency. What enabled me to decide on not having surgery was the neurosurgeon's saying, with considerable emphasis, that I might elect to have the surgery, only to discover post-op that my balance hadn't been impacted one jot. Interesting business, isn't it, trying to life a full and fulfilling life, with a woozy balance? Keeps us on our toes, doesn't it (pun unintended)? Best wishes, Ray (@ray666)
