So - I am still not completely clear what's wrong with me, and the doctor has prescribed a bunch more tests.
The first thing I did was breathe into this machine - which gave me a "Spirometry Report" I asked for a photocopy (like I actually understand anything on it), so if anyone wants to know anything about my breathing - I have all the report data in front of me.
Anyway - the # that the Doctor was concerned about was my lung exhaling output (or something) which was only 55%.
He also heard a heart murmer - and wondered why no one had told me that I had it until now (I'm 31).
So he wrote Rx's for Albuterol, Asmanex, and a Peak Flow meter.
He wants a chest X-ray, an echograph test, and a halter test done.

That's it. I took a couple puffs of the albuterol before my ride this morning, and had a lot of phlegm and mucus - which I don't usually have. Does that mean the albuterol is working?
