I got certified about five years ago, and initially, I was equalizing like most everyone - pinch my nose and blow into it. However, at some point, during a liveaboard in the Philippines, I got congested after a few days of diving and found myself completely unable to equalize. Fortunately we were near Dumaguete and there were a couple other divers on board with ear problems, so we took a ride to a local hospital where a doctor saw me and prescribed some medicine - don't remember what it was. After another day, I was able to equalize again, albeit with significant difficulty - I was blowing into my nose with every little depth change, both up and down, and I could hear squeaking inside my head as air was getting forced from one cavity to another through barely-there openings. Fortunately, after a week or so, this cleared up completely, and ever since then, I found myself not needing to equalize at all anymore. I can drop like a rock from surface to thirty meters, or seesaw between twenty-five and five meters as I'm chasing down a photo subject, and all I feel is a tiny hint of pressure in my ears that immediately releases by itself with a barely audible puff. Am I just fortunate, or could this be an early sign of some other problem?
