So the past week my lungs have hurt and i've felt short of breathe. My rescue MDI and Advair don't seem to be help. It kinda feels like someone is sitting on my chest, is this asthma?
well good for u, ASTHMA no, and at 800 on your peak flow meter; I have never seen an 800 on those meters and I have never AT LEAST IN DECADES got over 550
best wishes
