I've been diagnosed with bronchitis and given inhaler (salbutamol - 100pch) and beclometason-dipropionaat - pch 250 to use with a aerochamber. After several days, I'm not noticing any difference. Additionally, this is not acting like my normal bronchitis and I'm concerned that I might actually have Pertussis instead - the cough is very different -- not productive, asthmatic, and I cough so hard (especially when I first wake up/sit up) that I gag or nearly throw up. Not sure what to do as my doctor doesn't seem to want to entertain any other diagnosis. What would you suggest? How would I tell the difference between Pertussis and bronchitis and how long am I contagious if it is pertussis?
