what your experiencing could be Spinctor of the Oddi Dyfunction or the syndrome which your body misses the gallbladder (i forget what the syndrome is called).. last summer I spent 4 months going to every doctor imaginable and they couldn’t find nothing wrong and I had every test out there. My gallbladder was removed in 2008. No doctor could help me. Your liver is working overtime. I get tons of gas belching and shoulder pain. Plus at times I get nausea, loose stool, phantom pains, tiredness, pain under right rib area. I did find out that my liver enzymes went up slightly which is a sign of SODS. I have to eat a whole different way and i take Welchol to absorb the bile in my stomach to stop the loose stool. Gas travels everywhere and can be very painful and it even can give you shoulder pain.
