question: i have had a pain that can come and go but the pain is usually in consistently the same, never terrible enough to stop doing anything that I am doing, but it always comes back.  it seems to wrap around my lower right rib and can end up on my right side of my back.  When i stand up and move around it goes away, but sitting usually makes it worse.  pushing on the area gives me no pain.  I have had a ct scan, and ultrasound, but nothing is showing up.  of course, i worry it is the most terrible thing, like a large tumor!  I have had this for well over a year and 1/2.  I have been seen by a doctor.  No bowel problems either.  I thought it was my gall bladder, but the ct scan revealed nothing.  I even had a PET Scan a year ago June, and nothing.  I'm feeling paranoid because it's constantly on my mind.  Any ideas?
