No spinal tap. Had bloodwork done that neuro said showed everything (and I don't remember exactly what everything included without digging it up, but I know arthritis and Lupus were ruled out) was within normal ranges so auto-immune was ruled out. Did Alan show normal ranges in the bloodwork?

My toes becoming claw-like instead of hammer-like is what I believe made him suggest the genetic test. Or, maybe it was just to give me something to do until my next appointment.
