Sudafed, Doc's, Surgery, Pro Ear???

After 75 painful dives I am asking if you know if there is a cure for
equalizing problems? I have tried sudafed, practice, exercise & Doc's Ear
Plugs with little helping effect.

Today while ice diving, I could not get my left ear to equalize, ruining
three hours of preparation for myself, my buddy, rope handlers, safety diver
and other support staff.

I truly love this sport to the point of fanatical obsession and never want
to give it up, but my equalizing problems make life miserable.

Have there been any medical breakthrough's? Medicine? Surgery? I have read
a few articles on the DAN website, on estuation tube surgery that may help
but cannot find any additional data on it.

What about Pro Ear 200 goggles? anyone have any luck? Pro Ear's website
store wants $169. Scuba Toys and LiesurePro have them for $49.95. Can they
be any good for $50? What about general mask quality versus normal masks?

Thanks for putting up with my cross posted ramblings, but I am at wits end.
All comments and suggestions are eagerly accepted.
