I had more pain in the back than the front, and I found a little relief
by leaning my back against a wall. I was doubled over in pain
at times when I was having an actual gallbladder attack after eating two bites of cheesecake at a party. The attack pain lasted 30 hours, but by that time I had already had the gallstones seen on an ultrasound.
An abdominal ultrasound could check your liver, gallbladder, pancreas ... It is less expensive than a CT scan.
