--in compression neuropathies like radiculopathy. Even in non-compressive neuropathies, some nerves may be affected more than others and one doesn't necessarily experience a "wrap-around".

On other thing--healing nerves often produe similar symptoms to those that are being damaged. It seems as nerves re-grow and try to re-connect, they will produce abnormal sensations it take the brain a while to adjust to and re-interpret (on this board, I, Brian, and I believe others have experienced this). These sensations may be hard to distinguish from those of continuing damage, except in long term retrospect.
