I’ve felt like I have to cough 24/7 for the past 3 days and there is no pleghm but I do hear a very slight whistling when exhaling very slowly I do use an ecig and have for 4 years but this was a sudden onset and I feel it in my upper chest almost near throat that I have to cough all the time, I just took a mucinex medication and it helped slightly this did start happening after a grass fire in town as well.
