This is a repeated story over, & over.
The surgeons who made the mistakes will never admit it as such,
just a 'surgical complication'. (or act clueless as to your plight)
They always say it will heal in anywhere from 6 weeks to 3 months,
but we have posters here who have had the 'complication' persist for years.
Sometimes it is reversible if you get a neurosurgeon who really knows what s/he is doing and understands the situation.
