Hello. I was diagnosed with a mild hiatal hernia years ago with an upper GI. Over the past several months I ve had more pain in my chest and shoulder and back when I eat. Worse by night. I am on pantalaprozole and zantac. Still have same symptoms. I just had tests for my gall bladder which were normal. So now my Dr is finally sending me to a specialist, but not for 2 months. I m suspecting a paraesophageal hiatal hernia bc of my symptoms. Everything I eat causes pain in my back, & my food feels stuck, sometimes with nausea. I m worried about waiting so long to see the specialist. How do I know if I should go to the ER? And what can I eat or what should I avoid doing in the meantime?
