How do you know if you are on to high of a does of Flovent? I was on (2) puffs of Flovent HFA 110 Mg in the morning. I developed some breathing issues and my Pulmonologist increased it to (2) puffs TWICE per day -- I have been doing that for (2) months - and it has NOT helped the breathing issues at all (think they are related to ACID/REFLUX). Anyway I recently (past two weeks) have started to have weird upper chest issues??? Wondering if maybe I do not need so much Flovent - how do you step down from it gradually? Thank you ALL....
