Oh, I forgot to tell you that, given the pain that you are in (regardless of your bowel issues, you should not have pain once your gall bladder is out, at least not high up like that), you need to talk to your surgeon about it. It is possible that your bile duct was damaged when they took your gall bladder out. Or, if you had stones, you may have had a stone lodged in the duct when they took your GB out and it's still there. You need to talk to your surgeon about this lingering pain and see if he thinks it might be a surgical problem. I guess it's even possible to develop scar tissue that causes problems (and thus pain) or is even painful in and of itself.
When my gall bladder was bad, I would hurt up into my right shoulder and down to my right elbow and across my diaphram, so yes, GB pain can radiate to most anywhere in your upper torso.
Also, have you tried anti-gas meds? Gas can often get trapped under the rib cage and hurt into the back and chest. I know when I had my GB that I had a hard time passing gas for some reason and would get bad gas cramps. It may be that you have a similar problem and that's the cause of your upper torso pains.
