I, too, had gallbladder problems.  I actually had a doctor ask me if I wasn’t pregnant!  When I was 27, I pushed for an answer to my pain (the pain started at 19).  The "research" says you should be older, and over weight....not slender and young!  Anway...I finally had some testing done and had my gallbladder removed....thank goodness.   The pain is now gone!  Keep pushing!  Gallbladder "problems" are genetic....both my mother and grandmother had theirs removed!
