“Pain in center and to the right under my breast bone and in my back and upper right shoulder” sounds like pain that originates from the gallbladder (“colica biliaris”). Beside gallstones, bile pain can be also caused by certain functional gallbladder disorders. A HIDA scan can help doctors to reveal if there is a functional gallbladder disorder causing your pains.

Pain like you described can also be present in case of a peptic ulcer of the stomach or duodenum. Only an upper endoscopy (gastroduodenoscopy) can confirm or exclude presence of a peptic ulcer.
