Lately I've been having a really tough time with my lungs. 2 months ago i came down with a bad cold that a month later turned into acute bronchitis. I was treated with antibiotics and the usuall stuff they give you, and it seemed to've went away. But a month after the infection cleared up, I notice that every night I experience a whistling sound when i breathe, like I'm still wheezing. It always comes on right before i go to bed and continues all night--it used to be really bad but it's very gradually easing up, but not as quickly as I'd like and it's concerning me a little.
Could this be just a lingering effect from my very bad case of bronchitis, or could it be something else? I'm 21 and don't smoke, it's strange why I'm having this kind of problem...
