Detailed Answer:
Hello Dear patient,
Thanks for choosing HealthcareMagic for your query.
Have gone through your details and i appreciate your concerns.
Most likely you are suffering from irritable bowel syndrome with overlapping fecal incontinence.
Its not gall bladder stones.Pain in gallbladder is radiated to shoulders and gallstones are almost lways evident in ultrasound( yours was normal)

IBS on the other hand is diagnosis of exclusion i.e when almost all tests are normal patient is considered to have IBS.
Firstly small briefing for Irritable bowel syndrome and why every patient is a unique case when we deal with IBS.
In IBS there is some problem in the functional ability of the gut that leads to the symptoms of irritable bowel syndrome.
