pain in right side upper quadrant, just @ rib cage,feels like there is pressure there, onset pain started last week, on a 1-10 scale pain @ 3/4 just bad enough to take motrin several times a day, may have been onset from sneezing attack, bothers me more when sitting than standing , i do have dr appt tomorrow. breathing is somewhat difficult on r/s, no other issues, no pain anywhere else, all other body functions ok, please advise, i know you can not positvely diagnois over internet but opinion would be great
