I am not sure if you have been previously
diagnosed with Diverticulosis
and also as
having Gallstones.They can occur together.
Your main symtom seems to be nausea,vomiting
and diarrhea.If your abdominal pain
in the lower parts, along with fever, chills, even
some blood &mucus, that is more likely to be
a case of acute diverticulitis
If the severe pain was located in the right upper
quadrant associated with radiation to the right upper
back, nausea, vomiting,fever,chills and yellow jaundice,
more likely diagnosis is acute cholecystitis
In either event, you would have been admitted to the
hospital for further treatment.
They would have performed blood tests including complete
blood count, liver tests and pancreas enzyme tests.
An ultrasound of the liver& gallbladder and perhaps
a CT-Scan of the abdomen to look for abscess or rupture.
If they sent you home without doing any of these, I don't
think they can say that you had gallbladder problem.
It might have been a case of "Stomach Flu" or virus
Hope you are feeling better, if not, back to E.R. with this
I wish you well.
