I am (was) a healthy 24 year-old male and I just had my gallbladder taken our a few weeks ago.  I did not have gall stones, but my gallbladder apparently had some odd marks on it (not cancer) that made the surgeon feel that it should come out right away. Before the surgery I was constantly nauseous, throwing up, generally feeling horrible, and having an uncomfortable feeling in my chest (heartburn), feeling run down, and having difficulty standing up straight.  
This surgeon also had me do a HIDA scan, which came back negative.  I remember the woman who did the scan saying something about a possible problem with acid reflux (bile reflux?), but I am not sure what she meant.  She mentioned this during the uncomfortable portion of the test.  What sort of reflux problem can be seen via a HIDA scan?  What can generally be done to correct that problem?  My surgeon never actually viewed the images, because the place where I had the test done never sent them.  Can this sort of reflux problem be surgically fixed?  Another doctor seems to think that I may also have GERD, but the PPI and H2 treatments have not helped my symptoms to go away at all, and I have taken these medicines correctly for over three months now.  I am wondering if I have a different sort of problem or something. It is still hard for me to stand up straight (the heartburn is also still there), and I still feel run down, and I still get nauseous a lot and throw up from time to time.  Can you think if anything that may be causing these problems?  Any advice you can give me would be much appreciated. Thank you!
