Krista, I still have my Gall bladder, but my IBS started after surgery for a fibroid. If you are in that much pain maybe you should go to a another ER? Did they give you ANY meds? There sre so many other things it could be. What have you eaten today? Anything that might have triggered more pain? For me it's wheat, veggies, and raw fruit. Hope you feel better, and make an appt. with a Dr tomorrow to have some tests and rule out other problems!Laurie
