I have been experiencing shortness of breath, fluid retention, fatigue since 2005. I have not been able to fly in an airplane without getting chest pressure and difficulty breathing. After the flight, I feel ill and have chest pressure for several days. This all started with a respiratory illness in 2005. I had a fever, sore throat and body aches for a week or so. Things cleared up and I felt well for about a week but than developed an almost constant dry cough. i complained to my doctor but she would not prescribe an antibiotic. Felt is was a virus that had to run its course. A few weeks of the dry cough led to pains in my chest and a trip to the ER. The ER doctor said I was not having a heart attack. A few blood tests and a chest xray were done and I was sent home. I felt horrible for months after this episode. Fatigue, weakness, shortness of breath and an inability to exercise persisted. Stress tests, echos, chest CT and even cardiac CT and cardiac Cath was done. Nothing was revealed by these tests. I continue to have these symptoms. My life has not been the same. Has anyone experienced anything like this? I think it's heart failure or valve damage from whatever I was sick with in 2005 but nothing is showing up on the tests that I've had. I am now to the point where any exercise regimen that I try to start brings on symptoms of fluid retention, weakness, and shortness of breath.
