Have been having pains in my chest ,back abdominal area for 3 months . Went to the Dr. and had stress echo ,gall bladder ultrasound ,upper GI ,billarry scam(HEPA Scan),and blood test all done . The only thing that came back abnormal was the HEPA Scan . The GI has me on Prevacid but no relief . He doesn't seem to concerned about the H-scan. He says the bladder is working but not 100 percent . I still hurt 5 out of 7 days a week . It feels like my heart is going to come out of my chest . Is this a symptom of the gall bladder not functioning . Please give me some advice.
