I have had problems with shortness of breath for over 2 years. I have had many of tests, from EKG to breathing tests. And I still have not had any relief from this, I loose all concentration and can not focous on anything but the fact that I can not breath. The symptoms typically last all day, with only 1 or 2 days in a week that I do not have problems. The doctor says it is stress associated with anxiety and has prescribed all kind of anti-deppressants. None seem to work. I do not feel like I have anxiety problems, I just want to be able to breath.This problem affects me at work, when I am with my kids. I have also tried amino-acids. I am just out of options. Please help. I am 31yrs old, with no health issues, that I am aware of.
