Acid reflux and indigestion can also be symptoms of gallbladder problems... was your HIDA scan normal? For me that was the only test that showed something wrong, all other tests were normal, scans, blood etc etc... 7 months worth of tests... I had my gallbladder out in January and all my symtpoms went away...the surgeon told me I had a ton of scar tissue from multiple attacks (which didnt show on any scans btw) I was told by my GI and surgeon that gallbladder can be very tricky to diagnose if not stones as it mimicks alot of other diseases. It was also hereditary in my family... so id ask again.
To add to the statements, I was put on Zantac 75mg 2x a day and that seemed to work for awhile but then stopped working. I used to take Tums or Pepto and that has also stopped working
