I'm 18, not a smoker although i have in the past. I have acid reflux daily, i had asthma when i was younger but i mostly grew out of it. I have had many bouts with pneumonia and bronchitis. I also have anxiety issues. now, I have back pain between the shoulder blades and just under them, and pain in the centre of my chest permiating primarily to the right side of my chest. the pain seems to be where my lung is and deep breaths occasionly hurt. the pain in my chest feels like its in my ribs but its hard to tell, but my back pain feels deep, in my chest. any idea what the cause is? I've had an EKG (not sure if thats right but its the heart test) and its perfect. I've had a scope done which was also flawless. the doctors said that it was possibly an allergic esophages. but the acid reflux and gas has gotten much worse since.I also have many enviromental allergies but no food allergies that i know of although they do run in my family. The reasson im asking this is because the back pain is currently bad and its keeping me up.
