No I have not had spirometer testing, only a preliminary test into a tube. I will be following up with my doctor to get a referral as the inhalers do help a bit but not enough to make it go away and this definitely increased my fear that something more serious is going on. The symptoms phlegm seems to be almost gone at moments, and then other moments fills up, and seems to move up to my throat. Ultimately, looks like I am just going to need further investigation and testing.
