I have been having what feel like lightning zaps in my right breast. I feel tired and dizzy. I also had pancreatits about four years ago. I feel a pain where I would feel by upper abdomen but it doesn t go to my back. I do not feel nauseous but I do feel acids in the back of my throat. The zaps are random. I also take Celexa for anxiety and panic attacks. So I m not sure what this could be. Please help.
