I am 18, and recently i have developed some difficulty in breathing. It is not asthma. I visited the GP but he was unable to diagnose the problem. He confirmed that there was nothing obstructing my lungs and such.
I usually experience this in the day and i don't have this problem when i am asleep. Has this got anything to do with the heart? This is really a problem because it distracts me alot when i can't catch enough air all the time.
