Hi Minnietoty,
I can relate to your frustration with your doctor, I once had a GI that gave me a colonoscopy without medication and when I complained and cried she told me to "shut-up", needless to say I never went back and I am scared to death of another colonoscopy.
I completely agree with JulieBC, you need to do whatever you can to find another doctor who you feel comfortable with in every way. I noticed that you said that you are not a US resident, does that mean you live in Canada, just asking because I know that in Canada you can go to any hospital and get a list of doctors that are available. You can also call the Canadian Medical Assoc. for a list. Sometimes I think a recommendation from someone is the way to go.
Please do not beg this A--H--- for anything, he does not deserve you as a patient, I would even go so far as to report him for mistreating you.
The other thing is, you know that stress is not good for anyone with Crohn's, well just reading your post I got stressed out because your doctor sounds just downright MEAN!!
I really hope you can find someone else to see, and I would definetly not go back to this doctor because no physician should ever intimidate their patient.
Good Luck, and my heart goes out to you.
