I've had 2 different kinds of scopes. I didn't realize there was a "straight scope" one and a flex sig one. Jan enlightened me then explaining that my surgeon had done the straight scope as he probably doesn't have the training to do a flex sig. He had me come a year after take down and without any prep he had me literally pull down my pants, lean over an examination table and it was raised up so he could stand up, insert it, have a look around and was done. It left like a broomstick or baseball bat was shoved into me. I actually visualized a scene from "Deliverance" then. He did have some air of sorts to inflate it so he could examine me. I will NEVER have this type again. I had cuffitis then and found out when I went to my GI for a flex sig that I had c.diff as well. So IMO only do one without sedation if you aren't having problems or the doctor that is performing it does them without sedation. One of the without medication flex sigs was enough for me. I am becoming a weeny in my disabled days. Last year I had 18 little cavities as my gums receded, because of all of the medications I take. No longer a tough girl I requested and gladly paid for nitric gas, think that is what it's called, for the 3 times I had 6 cavities filled at once. I also took a xanex and some times a xanex during the marathon drilling events.
