I had to have emergency gallbladder surgery but realized later that I had symptoms for a whole year before that.
Eating things like pickles or real greasy foods would give me a burning gnawing sensation where the sternum ends and the stomach begins.
What landed me in the hospital and had to have emergency gallbladder surgery was a hot searing pain that I couldn't pinpoint if it was just below the sternum, the right-hand side of my back, or the right side where the liver and gallbladder rest.
A painless sonogram revealed that it was gallstones.
