I went for a colonoscopy yesterday. All I can remember is screaming because of the horrific pain at the Propofol insertion site. The Dr. Told me there would be " a little burning"! Had I not fallen asleep I would have pulled the line out. I am not a baby with no pain tolerance, but this was unbelievable!!! I need to go for more surgery and almost want to cancel because of only ?30-40 seconds of barbaric pain. Actually I am embarrassed for screaming like that but I couldn't help it. Anyone experience this, or know why it would have been so bad?? Thank you
