Hi Otter2154. Thank you for taking the time to read my message and responding. It is always encouraging to read what others have to say. She already saw a Pulmonologist, a Cardiologist and a Gastro doctor. She was subject to all kind of tests at SHANDS in Gainesville, FL but all the results were negative. However, since she continues to experience shortness of breathe, it is obvious then than an underlying issue still persists and must be determined. The sad and frustrating part is all these doctors who saw her, literally gave-up and did not give us other options or venues to explore in hopes to find the solution. I am not giving up, of course but it is extremely difficult to find the right path, particularly when there is no professional guidance. Basically, we are on our own but still fighting. Many thanks, again.
