???gallbladder

First time here. Just a few questions. I have only recently (past three weeks) been dealing with some new pain that I can not get answers for. I had an "attack" one night where I had this crushing pain as if my bladder was being ripped apart. The next day that was gone but since I have had terrible pain under my right rib, swollen abdomen, soreness in the area under my right rib, terrible gas and overall felling of flu like symptoms. Very nauseaus the last two days also. I have always had a very easily triggered stomach but this has been different. I have been having numerous bowel movements each day, some clay colored, but not dirrhea. It's has gotten to the point that I just don't dare eat for fear of more pain and bloating.
Been to the doctor 3 times, had us of gallbladder and liver and bloodwork, both negative. No throwing up yet, low grade fever at times though. I have this sensation that I have swallowed a grapefruit and its lodged up in under my right rib, even when there isn't alot of pain going on. any ideas? Tweet
