Laminotomy Recovery?

Hello! I am scheduled for a Laminotomy to relive the symptoms of numbness & intense heat in my pelvic area and left leg (cauda equina syndrome). I am over 70, have stenosis, scoliosis and osteoporosis and am fairly active: swim, Pilates, weights machines, elypical machine. I used to walk for an hour a day, but my symptoms are making that difficult. Has anyone had a laminotomy? How long is the recovery? Any info or tips would be helpful! Thank you.
