I have just been in for this procedure and everything was going well until the doctor tried to insert the camera. The pain was unbearable and had to demonstrate by digging my nail into my hand with force to show that it was nothing compared to the pain of the camera going in. It felt as if it was tearing through skin. I'm so sorry to post such a negative response but feel so alone with this. My wife was furious with me saying it must have just been my anxiety which it really wasn't.
I'm glad that other posts were more positive but now worried why mine was so excruciatingly painful.
Would love to hear from others if they can help.
