I never got in depth with my post-op care and I should have. I was in such pain and they couldn't get it under control after neck surgery. I screamed my head off for hours. They gave me one Perc 5MG every 3 hours, it was horrible. I.V pain meds go through your system in minutes. Dilaudid lasted like 10-12 minutes and it was gone.
I would suggest having a deeper discussion rather than just saying OK to everything, I wish I had.
