Anus pain/discomfort/stimulation

hi im new to ibs! i dont know if this is what i have! but ever since i had my gallbaldder removed everything i eat makes ny stomach churn! i get diahrrea!but for the past week! ive been having this discomfort in my butt hole or colon however you call it! its not painful but feels like a discomfort or like a stimulation and sometimes just a weird feeling and then it makes my lower back and lefs feel ache! anyone had this???

There are two possibilities: either IBS or bile acid malabsorption which causes diarrhoea. Both are common after gallbladder removal. See your doctor and ask for a SECHAT scan to check for BAM which can be treated. Have you seen your doctor already about this?

hi i had my gallbladder out about 20 years ago by keyhole surgery, my bowels have never been the same since when it comes to eating.
I have tried gluten free and dairy but nothing helps.
Have you tried anything at all?
I was diagnosed ibs and cannot find a solution.
