are you sure it's blocked on the outside and it's not the inner part that's causing the probs? I've used almond oil and then warm water in the 3 jet thing which i'm assuming is the one you're talking about and it's always worked fine. I was at the docs at the beginning of the year w/ a tinnitus type thing and it was apparently an internal eustachion tube issue. unless you can actually see some compacted wax in there (dunno what would be compacting it though) i'd suggest you try and leave it alone in case you damage something by chasing erroneous symptoms.
of course, could be it's not wax, and is actually a big spider.
There's definitely a wax block there, the Mrs can see it (I know she's the one for me after the crap she's fished out of there recently ). I can't say with 100% certainty that's what causing the block but considering the history, a very likely bet.
