Hello, I write from Africa, I am 38 year man with pain in the chest and feeling that I cannot take in enough air. However, the pain in the chest does not increase as I am active, however sometimes if I walk up some hill or some stairs, then afterwards I must stop and breath...unlike just 1 year ago, this is new to me. I have been fortunate as my country is very poor but I have been checked inthe hospital with some blood testing and ultrasonic heart measuring, as well as ECG tracings. I was also put on the treadmeal to run with ECG tracings and blood pressure, the stressing test. I also blow air into a machine to test my lungs. No problems have been found with the testing, and I have been told I can no longer be evaluated, now I don't know what I am to do?
