It happened on my Inspiration with OTS lungs and it seems to occur more when I use BMCLs on my Inspiration. A pressure difference could be causing it, but I'm not sure why and how.
if the BMCL are too low down the back, a squeeze sensation might be experienced by some.
the other thing i thought of is, that the glottis is closed and catching for some reason when exhaling
do you notice whether its more of a problem on inhale or exhale?
i must be trying to avoid work with all these questions.
anyways something to ponder.
i guess if you're not getting hurt or feeling sick and its only a temporary/intermittent problem then its probably not too serious.
