been having pain in abdomen, upper center right side right below the rib cage, it's been going on for 3 days . had blood workup/ and an abdominal ultrasound,(yesterday and today, waiting on results) no vomiting, no blood in stool/urine, no temperature, some diarrhea and i sometimes have reflux? just pain tender to the touch in that specific area? . what could this be? / any ideas? should i be worried.? could you pull a muscle in that area/ would an ultrasound show this. or inflammation? an infection ?or a cyst ? or something like that? or form taking too much Tylenol? or food poising? feel pretty good other than pain. ?/ any ideas. thanks for help.
