Could Pain And Bloating Of Abdomen After Having Food Be Due To Problem In Gall Bladder?

I have been treated for acid reflux with Dexilant for years. In the past few months, I have had burning, sharp pain in my right side. I have pain that radiates to my back and up to my shoulder. I ve had pain over my right eye also. I only feel normal in the morning. As soon as I eat the pain and bloating begins and intensifies. It keeps me awake at night. I had an ultrasound and an abdominal CT recently. It didn t show anything so my gastro doc put my on Linzess. I was also prescribed a magic mouth wash to swallow up to four times a day. I feel worse! I m exhausted, chilled, no appetite, loose light colored stools and more intense pain and burning. I think it s my gallbladder. Is there a chance that the tests are incorrect? I m in general good health and not over weight. I m tired of feeling like this!
