Yep, unfortunately in some people - particularly those with spastic colons - the air used for the contrast can the pain you describe. All you can do is wait to pass all the air and barium. I had the same problem during a BE. Just awful, isn't it? Bad enough it's such a degrading and humiliating test, but to have that kind of pain on top of it is just... well, there isn't a strong enough descriptive word I can use on a public forum! Hope you get all that stuff out of you sooner rather than later. :-)
Thank you that gives me peace of mind to know that it's not uncommon for we "spastic colon" sufferers. I am barely feeling better now that some of the barium is gone, but yes so humiliating...I thought I was going to faint at one point. I appreciate your responding.
take care
