I know this is an asthma forum but not sure who to ask so thought I'd put my story out here and see can I get any tips.
I went to my own GP 3 years ago with a chronic cough (ongoing about 15mos by the time I presented - I study abroad and had been told in that country my cough was psychogenic, i.e habit cough and to take some cough suppressants...which didn't work).
PF was minorly down (420 when estimated for height was 490 apparently. So was started on Ventolin and got a chest x-ray which was clear. Cough didn't really abate so was stepped up over next few months to reach Symbicort. Within 3 weeks of starting on this noticed huge improvement in my fitness, no longer got short of breath when running or at swim training, etc. Cough persisted in morning and night but that was it.
Shortness of breath has since developed into affecting me any time. For the last year I've been using my blue inhaler 2-3 times a day on average, some days a month I need it 20+ times. Wake up some nights. Winter is far worse and frequently get "chest infections" or viral infections as well as exacerbations of my "asthma".
Been to doctor where I study but no wheeze=no asthma so always just been told to keep taking my inhalers. This October got a chest infection and was put on steroids, ended up in A+E with it. Got a referral to pulmonologist and when I was with them recently spirometry shows "mild obstructive pattern" but isn't below the criteria for asthma (FEV1 = 90%, FEV1/FVC = 75%), so looks like my lungs are working fine. Reversibilty is 6% (needs 12% for asthma dx). PF's never drop below 440, best is 510 so green zone there.
The doctor thinks it's all postnasal drip. Cough still there but much improved since I was given montelukast. Have been on a nasal spray for 3 years. Any suggestions as to what could cause the shortness of breath or does anyone has experience of getting short of breath with chest tightness and coughs related to post nasal drip? Any suggestions on how to improve this or what to do. Many thanks in advance!
