Hi
I went through your history. Although you haven't mentioned your age and gender, but your history is consistent with SOD (sphincter of oddi dysfunction) until and unless proven otherwise.
Despite your
gall bladder surgery, you can have such type of abdominal pains in SOD.
Sphincter of oddi is a valve present at the end of CBD (common bile duct) that relaxes once you start eating so that bile juice can reach
small intestine. In SOD the valve pressure is high and it does not relax and therefore you experience pain.
To confirm the diagnosis you have to perform your LFTs and a
MRI known as MRCP.
If both LFTs and MRCP are abnormal, you should
consult a gastroenterologist to undergo a type of
endoscopy, ERCP which will be curative as well.
If either LFTs or MRCP is abnormal, you have to undergo a confirmatory test that is called monometry. And if it's abnormal you will need ERCP with sphincterotomy, which will be the definite treatment.
Hope I have tried to explain your condition to you in simple words
Regards
