BTW - one anomaly with my own condition is that I can still hear 16KHz in the affected ear...odd.
The ear that's currently affected has been gradually bunging up over a period of time, to the point where it's at now which is driving me mad. It feels as if something has gradually 'grown' in the ear, but an MRI has ruled out a nasty such as a neuroma.
The other ear is the one I've traditionally had blockages with, and it's been fine for ages and is now better than the other...
