 Even as recent as the 90s, they used to excise nerves all the time on people. I met a poor lady that had a horrible hand neuropathy, and so they went in and snipped the nerve. And then they had to go in three months later because the pain was so severe, they snipped it halfway up her forearm, and then they snipped it at the elbow. And then they kept following this thing all the way clear back up to the nerve root, wondering why it wasn't giving her relief. And the problem is nerves get angry. They do.
