Oh god, that reminds me of a funny thing that happened to me after surgery. I had finally been taken to a room after being parked in a hall for hours. I was dying of thirst and I managed to pour some water into a cup and gulped it down. Well, THAT was a bad idea. Immediately the cold water came barrelling back up my throat, and I learned a new term: "projectile vomiting." I puked all over the nurses who were just standing there ignoring me. I was really trying hard to tell them something bad was going to happen but they didn't care. And if you can believe it, THEY blamed ME!
So much of what happens when you decide to take control of your life is about not depending on help, even from those who are being paid to do so. So before surgery, do a lot of research and ask a lot of questions of your doctors and professionals on the internet. A sharp pain in the side is something I've heard a LOT of our members complain about. But I would still call the doctor or go to initial care. Pain meds are great, but they can also mask real problems that need hands-on medical attention.
I used to always say this, and I'll say it again:
YOU'RE NOT A DOCTOR.
Leave pain to the professionals. That's what they're there for.
