Why can't I laugh without coughing violently?

I have been dealing with this issue for years and have been told that nothing is wrong. I can not laugh anymore without coughing violently. I do have a history of allergies and no history of asthma. It hurts me and seems to only be getting worse. I was told that it may be a sign of asthma, but why now? When I start the coughing episodes, I notice that I have some sputum, but I don't let it out. What could be causing this?

I see the questions, where do i read the answers and or suggestions of what the symptoms might indicate is wrong.  The comments of Mrs. Evans on Nov 26, 2008 are the exact same symptoms I have but mine have been going on for months. I never had mucus until recently and I wheeze at times mostly when lying down.  Not only can I literately not laugh at all without coughing sometimes, unless very calm even talking presents a problem.

I have the same issue. I stop smoking cigarettes when it start shorten my breathe. I can't laugh or talk without coughing so much I feel as if I'm going to throw up. I do have mucus. I also can feel myself wheezing whether laying down or standing up. I'm constantly out of breath.
