I know everyone's experience varies, but if this reassures you at all -- I was surprised by how little pain I experienced post-surgery. The most discomfort was in my throat for the first few days and that eased every single day. I had some soreness from the incisions but never felt acute pain. The pain meds in the hospital took care of that. When I returned home, I'd feel some soreness occasionally and would take a dose of the pain meds. I don't think I ever took more than one dose a day, usually at night. That only was necessary for a few days.
Hopefully you'll be as pleasantly surprised as I was!
Good luck to all of you!
