Please share about severe cervical spinal stenosis

I'm new here and having surgery at Phoenix Mayo Clinic on the 30 th, just about a week away. I know so little about it all except it's essential. I'm a 75 year old woman with C4/5 and 5/6 discs getting removed and two cages put in somewhere. The info has been so brief in one 15 minute visit with the surgeon and I'm now scared. I have had so many health issues lately from my Lupus/mixed connective tissue problems, ddd and severe headaches, PVC's that drive me crazy and blood pressure ups and downs, mostly downs.
I'm hoping to get through surgery then attend to the rest of the story. I'd like to know how the recovery is from this anterior approached "release of my spinal cord" and what to expect pain wise. I'm alone and starting to feel afraid.
