I've experiened a similar, or same problem in years past.
>>>SOUDED LIKE I WAS IN AN 130+DB TECHNO CLUB THE PREVIOUS NIGHT!!!<<<
Mine was simply the aural canal being piched closed by the weight of my bulbus head. The ''ear wax'' would keep the canal closed until I would pull straight down while touching just below the outer ear.
The going phrase is ''do not put anything smaller than your elbow in your ear''.
It seems keeping it dry, and perspiration free always helped. However I have not experienced the problem, in about two years. It happened several years before, and only ever lasted, no more than a couple weeks at a time.
