i havent no, have you tried ear candles? they get rid of alot of cr@p out of your ears!!
they are a little bit expensive but maybe worth a shot??

i do notice my ears "crack" alot though!
yeah, haven't tried the candles only coz i think their mostly for wax. Doc had a number of peeks in my ears, reckons there's not a skerrick of wax in there but can see the fluid behind the ear drum. Problem is that it's not draining out of the eustachian tube due to them swelling (hence scripts for corticosteroids and nasal sprays )
He reckons all I can do is keep treating with the sprays and such until after i deliver but is so horrible, like living in a tunnel Wondering how other people are dealing with it and if they had it in pregnancy if it went away after delivery...
