What is this severe abdominal pain???

It was not my gallbladder (I don't have one).  Turns out it was the prednisone I was on!  It was doing SOMETHING to my stomach because it hurt almost every time I ate unless it was a teeny tiny amount of food or chocolate.  :/

Go figure, though.  None of the doctor's ever thought to take me off the prednisone.   My stomach is much better now and I only have pain if I over eat which is rare.
