I asked my surgeon for the same thing and got general aneasthsia anyways. I had a horrible reaction to it, I knew I would. I find it hard to believe they will do surgery like this without general. I complained to the chief anasthesiologist, she apologized and moved on.
Since I recovered I did not sue but sure felt like it.
Make a call to your Dr and ask him/her if it's safe to take these meds. You will be getting pain meds in the hospital. They will also send you home with a script for pain. Remar
