I hate to say it, but they were pretty similar to me. My problems were long ago, before surgery. My gallbladder was a very intense dull (does that make sense) pain in my mid-section, a pressure. I was sweaty and had to keep leaning back to get my breath in.
My ulcer pain would radiate to my neck and back (mimics heart attack in a lot of people) and be very sharp.
I guess on thinking about it, the gallbladder pain went down on my body, my ulcer pain went up.
Don't fool around with this. go to the ER.
