First of all. Sorry about the long post. I'm a bit confused about what's going on with my health here. First a bit of background info. I had a cold early in the fall, and was never able to shake the cough. Went to the dr after having been coughing every single day for over 6 months. Dr prescribed me a blue and a brown inhaler and said that I had infection and exercise induced asthma. Used the brown inhaler every day as instructed. The cough was significantly reduced, but I still haven't gone a single day without coughing. To clarify: I went from having many coughing fits a day where I couldn't talk and almost puked, to just coughing "normally" once or twice a day.
Went back to the dr for a follow up a few weeks later. We did a spirometry before and after ventoline (while I was on the brown inhaler). Had FEV1 of 81% and FVC of 104% or something, but no significant change after ventoline. I did however cough up a bunch of mucus a while after the 2nd spirometry, which I usually do a while after taking the ventoline. Dr said since there was no change, he couldn't give me an official asthma diagnosis, but told me to keep taking the brown inhaler for a few more weeks, then stop. I tried stopping the brown inhaler for a few days to see if the cough would come back, which it annoyingly did.
I don't really have any other symptoms other than cough. I do get a slight whistle at the end of each exhalation at night every once in a while, but I can't tell if it comes from my throat or my lungs. I never really feel short of breath or tight chested, but I did have a constant feeling that I had to cough when I wasn't on the brown inhaler. I have post nasal drip and some diagnosis in my nose which I got when I was a child... Rhinitis or sinusitis or something. Don't remember, but nothing helped against it. I also have multiple allergies and I had childhood asthma. I'm seriously dreading going off the brown inhaler because my life has gotten so much more comfortable after starting taking it.
So I'm wondering; if not asthma, why have I been coughing every single day for 7 months? That can't be normal. Why are the meds working? What is my doctor thinking?
