Hi-
You might want to look up a cervical spine nerve map and C4/C5 nerve root compression.

I have leg symptoms and issues walking/crutching and in my case those are partly related to multiple cysts in the lower back in the lumbar and sacral spine (L4-S4.)

The generally with nerve compression is that the longer it's there, the less likely and longer it will take to recover because nerves grow slowly. But there are always exceptions.
