Welcome to HealingWell. I am sorry to hear of your problems. It appears you have been through the whole work up of GI, Cardiac and Pulmonary without finding anything to explain away your sx. I know this must be terribly frustrating and alarming for you.
You might talk with your pulmonary physician re a Diagnostically, flexible fiberoptic bronchoscopy. Fiberoptic bronchoscopy is a procedure that allows a clinician to examine the breathing passages (airways) of the lungs. Fiberoptic bronchoscopy can be either a diagnostic procedure (to find out more about a possible problem) or a therapeutic procedure (to try to treat an existing problem or condition).
Common reasons for a bronchoscopy would include unexplained symptoms related to the chest, such as persistent cough, coughing up blood, wheezing, hoarseness, noisy breathing, or shortness of breath. The airways are examined for signs of problems and samples of tissue (biopsies).
Let us know how you are doing and keep on posting here in the forum. We are here to support you.
