Have you ever had a barium cat scan...?
its a ct but they make you drink barium
first and ti flows thru you system and fills
the small and large intestine as well as the
stomcah and then under the ct scan it kind of
glows in a manner to speak but what it does is
shows blockages if they are there.....the best
thing sometimes is to stay on the doctor and keep
repeating yourself...either that or look into
seeing a GI. Some times pain meds to cause
conspitaion mine sometimes cause me to feel like
i have to go when i don't but they have a while
differnt effect on me than they do on most people
