question: hello, I am 20 years old healthy male without any history of breathing problem. Last week I went for a Bar B Q...and the following night i developed a breathlessness problem...I am not able to breathe normally...I am taking short breaths....I had my lungs xray done which turned out to be normal..blood tests and ecg are normal too...blood pressure is normal as well..i want to know what is the exact problem and how many days can it take until i can breathe normally...Also i do not have any fever or pain in the chest...only short breaths...thank you.
