Good luck Cat!
I had my hemilaminectomy/microdiscectomy a year ago (and I no longer shovel snow...). It took about two weeks to get back to work (I wrote GenINI while I was down), but about six months to really feel right again. And yep, numbness and tingling that comes and goes to this day.
Don't be afraid to ask for an anti-inflammatory if you need it... it helped me a bunch (though I was monumentally grumpy for a week from the methyl prednisone). Also, definitely look into physical therapy, and actually do the exercises and stretches!
Take care,
Joe Z.
