I have a pain that goes from the right to the left of my back, under my shoulder blades. It started coming on slowly, but now it goes through between the shoulder blades and through to my chest. It feels like there's an open cut, round area being filled with acid or like some alien creature chomping away at my insides. I've been to the emergency room and all of my organs have been checked. I do have a hiatal hernia and acid reflux, and trouble swallowing. My doctor says I need to go to a pain clinic, but there's a wait to get in. Can anyone help me figure it out?
