Just two bits that haven't been covered too much:
1. a purge mask *may* help, but don't buy one with that expectation. I have used both, and find my non-purge mask both leaks less (the purge mask's valve isn't 100% anymore); and the non-purge mask is *way* easier to clear.
2. Sudafed. Well, you can see my post here: http://www.scubaboard.com/showpost.php?p=1843439&postcount=14 for a bit more background, but the bottom line is that it can "wear off" while diving in less than an hour. This person took it topside, about a half-hour before our second dive, and by the end of the second dive (56 minutes) it had worn off enough to cause a reverse block, which she suffered under at least until we got back to the dock 30 minutes later.
Oddly enough, I generally have slightly congested sinuses, and have taken Sudafed before diving -- at one point, almost habitually. Partway through my last trip, I forgot to take it in the morning, and clearing my ears was easier!.
I'm concerned about what you mean when you say "it just went from bad to worse after that" -- what happened that made it all worse?
