My husband has very similar symptoms as
you described for the past two years. He
get severe abdominal pain above his waist
and below his chest.
It radiates around his back as well. He
too has had blood tests, colonoscopy,
ultra sound, MRI, x-ray, cat scan,
endoscopy with biopsies, and all come back
negative, but yet the pain persists.
Sometimes the pain is so bad, that he
vomits. It doesn't usually last for very
long, but appears to happen within a half
hour or so of eating. No connection
whatsoever to a specific food. It can
happen if he drinks water! The doctor
wants to take out his gallbladder. What
do you think?
