 I'll see him this Friday for a follow-up. And then another fellow I haven't seen for over a decade. He said, you fixed me once before. Can you fix me again? What's going on, I asked. I'm having this numbness and tingling. It's showing up in my feet or that it's in my hands or it's in my shoulders. It's in my arms. It's in my legs. And I'm sitting there thinking, multiple scurrows. That's the first thing that hit my head.
