In most people earwax is produced in modest amounts and migrates out of the ear naturally. But a few people such as yourself are, let's face it, freaks. You may be tempted to remove excess earwax with a Q-tip or the like. If that doesn't work you need to see a doctor. I mean, you gotta be ready for anything.
Some doctors say, forget all the apparatus, just squirt in some warm water.
But we'll leave those decisions to the pros. Now, about roaches crawling into ears. You may think this is some kind of deranged myth. Happens all the time. In fact, a controversy has raged since 1980 over the best way to get the little bastards out.
