Gil,
I wish you all the best re surgery but did not quite understand what surgery will be done. Is this a microdiscectomy and laminectomy or ???
Sounds like you need surgery re your exam and hope that all will come back afterwards.. don't rush the recovery as you have this chance to get better.
I tried to rush things post my 2nd discectomy and it did not turn out well (failed surgery/failed results and long crappy haul afterwards to get relief)...
So this is it buddy~ do it right! Or should I say that to the surgeon
