I Have Had Pain In My Upper Abdomen That Radiates

I have had pain in my upper abdomen that radiates to my back between my shoulder blades, mainly happens at night. I have had this in May 2014, had a ultra sound of my gallbladder and nuclear gallbladder test, which were both negative, but there is a history of gallbladder problems in my family and all of them have had them removed. My doctor put me on Pantoprazole Sodium thinking I have reflux and/or an ulcer. I stopped the medication about 2 months.
