This is very helpful, because I have had this cough for about a week that's been getting progressively worse, and today at work I had to step out about 7 times to hack out a lung, cough up some phlegm, then use my inhaler. When I cough sometimes I have this almost black-out thing happen, where I see spots and forget where I am and what I'm doing, that might be because I put so much stress on my throat to cough out whatever is giving me the cough, but i'm unsure. I'm going to the doctor tomorrow because I urgently need assistance, my sleep has been interrupted for the past several days and i'm currently functioning off 3 hours of sleep, but I can't stop coughing and wheezing, to make things worse I have asthma. It could be that flaring up, but of course, I'm not sure. So thank you for making this video nearly a year ago, because you've answered almost all of my questions.
