Freda,
Every surgery is different depending on the size, location. No two recoveries are the same.
But suffice to say, the first 3 days are not especially fun (we say the first 3 days don't count) but after that, it gets much easier.
Tell him to try and sleep through whatever he can, in between being woken up to ask him where he is
If he has pain, headaches, nausea, TELL THEM or you. Gotta try and keep it in control.
My surgery was 11 hours long (normal is 6-8 hours), I had headaches post op. Lots of IV lines, oxygen, cathether, but it all came out within couple days. I was up in a chair day after surgery, and walked the hall that day or the next.
No balance/dizziness issues because my other side had completely compensated. It is normal to have that dizziness though.
Hospital stay is around 5 days. Just bring lip balm, bathrobe, toothbrush. That's all ya need! Maybe some eye ointment if his eye is dry, but the hospital should provide that.
Hope that helps. I'm sure others will chime in
