Hi,
Thanks for writing in.
Brain surgery cannot cause peripheral neuropathy however spinal surgery can cause peripheral neuropathy as a complication. Did he undergo brain surgery or spinal surgery?
What was the indication for surgery?
It is important to identify the cause of neuropathy first and then the treatment can be decided upon.
Nerve decompression surgery is an option.
If all else has failed you probably should contact the Institute for Peripheral Nerve Surgery. They do Nerve Decompression surgery. Go to "****.***" and read all about it. Good luck!
