Hi M., I recently had surgery on my back. I knew my surgeon for 15 minutes or less before he sent me to the hospital through the ER for my surgery. I had already read so much about my doctor, I was really comfortable with him. Before I walked out the door, he said I will take good care of you and all I could say was, I know, I already read all about you. When he explained the procedure to me and asked if I had questions, I didn't have any because I read all about the procedure and really only had comparison questions from what I read to what he was actually going to do. I went to the hospital and had to be processed and 9 hours later, I had surgery without reservations. The doctor even told me in the surgery room I was one of his easiest patients.
I suggest you go online and read about your procedure so you are aware of the things they explain to you. I am not in the medical field, so had I not read about it, I would have been very confused with all the terms.
