I mean if there was longstanding evidence of the treatment working well enough and with low enough side-effects. I don't think we're anywhere close though. Think of phantom limb pain.

Do you have to amputate? My mom has had hip replacement surgery twice.

If it were a common, reliable procedure - yes. Yes I would.

We get surgery without blinking all the time in this country, and the most common types are incredibly safe. You make leg replacement on the order of knee or hip joint replacement surgery, and you’ll have people beating down your door.
