Sounds like what I went through with my gallbladder (in May). I had lots of mini "attacks" that lasted about 15 minutes or so until the last one that lasted over six hours before I was willing to go to the ER... Gall bladder... was taken out that week with four incisions, went back to work five days later. Now I can eat food that is spicy/fatty without ending up on the floor in agony...
