Hi Akila,
Very sorry to hear that you have that many problems. Not knowing your Crohn's history (did you have a surgery recently with the vale between the intestine and the colon removed? What meds are you on?), if you are in pain and you got lots and lots of diarrhea, the only thing I can say is you should contact your GI quite quickly and get treatment. I somehow doubt, but others can contradict me, that going to the toilet 15 times per day and being in bad pain is related to bile malabsorption alone, that sounds like quite a lot of inflammation and an active disease.
Hope you will be better soon. I see your post was from a few days ago, have you in the meantime seen your doc/GI?
