Hi Crystal.
Thanks for your query. Read the history and understood the problems.
You have a typical history of
severe pain in the abdomen where the ribs are.
As if somebody shoved something and it got stuck there, got alright when you rolled back. Pain is more on the right side where your
gall bladder was and has been removed 1 year back.
The probable cause of sudden and such a severe pain can be due to Volvulus of the Stomach
Bile duct stones
Intestinal obstruction.
I would advise you the following:
The only specific investigations which can help you are:
Barium studies for the stomach in head-low position to see for
stomach volvulus.
Upper GI endoscopy can help
Colonoscopy and CT scan of the abdomen are done to rule out other probable causes.
If volvulus of the stomach, simple stitch to fix the stomach to the anterior abdominal wall can help you the best and on permanent basis.
Rest of the treatment depends upon other probable diagnosis if made.
