Vasa nervorum

But, you know, the One of the big things that starts problems for nerve injuries is a disruption in the tiny microvascular circulation.

Especially when the nerve compression stops the venous return of blood flow to this area from the vasa nervorum, which is the little venous vessels of the nerves that return blood flow.

Just a minor, minor degree of compression can stop that venous flow.

And then you start having local hypoxic injury.
