About two weeks ago I developed a pretty bad cough. Lately I've found it difficult to breathe, especially in the morning and right after coughing. The phlegm that I bring up is clear and kind of thick. My lungs seem to be fine - no noise. A humidifier seems to help a bit, but I still sometimes feel that I'm suffocating, I wake up at night because I turned or stretched - every major movement seems to set off my cough.
Coughs come in two varieties-acute and chronic.
Coughs can be caused by four basic stimuli. That is chemical, infectious, mechanical, and thermal. Chemical stimuli are different environmental factors such as perfumes, cigarette smoke etc. Infectious have to do with the inflammation of the lung during and after infection. Mechanical is the cough caused by stimuli such as chalk particles, lung tumors, etc.
