Yep from what I know those are gallbladder symptoms. I'm not a doctor but I think if something were wrong with your liver you'd be turning yellow before you experienced pain. I could be wrong about
that, but gall bladder problems are far more common than liver problems to begin with, so...
Anyway my symptoms were different, which is rare enough, but the cause of my bad gall bladder wasn't stones. Normally, as I understand it, that's usually what causes one to experience the pain and all of that and stones are what the ultrasound is meant to find. In my case I did not have them, like I said, and the ultrasound came back looking clean as a whistle. But luckily I had been suffering for so long that the GI wanted me diagnosed as soon as possible and scheduled a HIDA scan almost simultaneously. Next day or something. Anyway, it came back with bad results and I was on the operating table in less than a week. Turns out that when they removed it they found a small, benign tumor that was mucking up the works in there.
Point is no matter how your ultrasound comes back, try to get a HIDA scan anyway.
