While I’m sitting on the exam table with my legs dangling, the neurologist reaches for a metal object. He’s already poked me several times with the safety pin so I’m wondering what he plans to do with this larger pointy thing. He grasps my foot and scraps the object on the bottom of my foot along the outermost side and under the toes. My big toe jumps and the other toes look like they are trying to get away from the torture device. I have just demonstrated a positive Babinski sign.
