I have had pain in my lungs for 8 months. I have just completed 7 months of doctors and tests for Acid Reflux to see if that was causing the pain since xrays showed scarring from asperating acid. The last test showed the medicine is controlling the acid and it isn't going into my esophagus. My pulmonary doctor did an EKG in August to see if my heart was okay since I suffered a blood clot 9 years ago. It was a medium clot that is still in my right lung. The test showed my valves were okay but the right side of my heart is enlarged due to the embolism. Could this be the reason the top region of my chest on the left side, hurts constantly? I am so frustrated and just want to stop the pain. It is bearable,but it really begins to effect your mental state after a while.
