so I was doing fine for 6 years, exercise and everything, until this week. Now trouble breathing day and night. My peak flow and fev1 are always normal at home with digital peak flow, but when at asthma doctor last month she told me it was at 60 abd thats why I need the Trelegy. I think they use fev6 measure. I posted my pfts here few years back and they weren't that bad. Not sure what to do now. Can't lose another job to this crap
