:? Sounds pretty weird - that you feel so congested, and the doc isn't hearing it. It also appears you have had pluerisy before? If so, you know what pluerisy feels like. For myself, pluerisy always hurt worse inhaling. Pericarditis hurts when I breath, but is at it's worst when I try to bend over or lay down. My asthma most of the time is at it's worst when I exhale, though not always.
I've had alot of respitory problems, and have learned to trust my own judgement. If you think you are ill, you probably are, even if at the moment you were in the doctors office it wasn't problematic.
I often have the "take the car to the mechanic, and the noise stops" experience and frustration. If you still don't feel well, make another appt. and have it checked again. Can't hurt to double check.
