Could there be something wrong with my gallbladder

I'm a 35yr old female. For the past 1yr I have been having what I believed to be severe indigestion. Never have I suffered with indigestion, only duringmy 3 pregnancies. Last yr I was having bad chest pains after eating and it fell like fullness in my chest.. I was on antiacids that helped at times. Saw a GI specialist that ordered EGD, which showed gastritis and was treated with antibiotics and rx strength antacids.. this helped for awhile. Periodically this happens with acidity fluids coming up. About 3 months ago I didn't feel myself, nauseated, fatigue. Dizzy, light headed, fullness in chest hours after eating and chest pains, symptoms worse when lying down . I saw pcp again treated with prilosec.2 weeks later I had a severe attack that led me to emergency room, I thought I was having a heart attack. Severe chest pain in middle of chest mostly on left side and under left breast, nausea, pain in my neck, throat, fullness. They did cardiac tests, ekg all this came back fine. Had appt with pcp 4 days later, couldn't eat I felt horrible after eating, I was gassy. Bloated feeling, as well. I was talking to a nurse friend and she said from my experience if its not your heart it sounds like gallbladder. Amazed cause I never had abdominal pain that was noticeable, but I did have pain and cramping that led me to bathroom 30-45min after eating but it got better after using bathroom. But my other symptoms outweighed these so I didn't mention. Called my Dr to order gallbladder ultrasound, that was fine showed no stones. 2 wks later GI Dr ordered hida scan. During 30 min effusion of CCK my right side of my stomach started paining and burning, I asked tech was this normal , she yes if it'd ur gallbladder, she states this med mimicked food.. hmmmm.I returned to work after scan and felt awful. My right side of abdomen was hurting and my back on right side below my right scapula was also for over 24 hours after scan. I was gassy, bloated and diarrhea. In a couple days I found out my gallbladder was 20% ejection rate and the low normal was 35. For a little over a yr after seeing pcp, Gi specialist I suffered and not once was gallbladder ever brought up cause I didn't have abdominal pain. It took a experienced nurse to gather my symptoms and suggestef gallbladder and pushed for me to convince drs to order tests.. and after talking to my mom, she too aty age had to have gallbladder removed do there's hereditary. So glad I know know that my chest pains, and indigestion symptoms was my gallbladder. Maybe my story can help someone, cause I don't know if gallbladder would have ever come up cause I wasn't having abdominal pains.
