Yes, dammit..

It is probably a mix of age and MS...AGAIN.....grrrrrr. Can you tell I'm mad about this?
I have that muffled sound in both ears, I think. Sometimes it's worse than others. I hear the sounds, but the words are not clear.

Turning up the sound only helps some, because it's not the loudness as much as hearing the pronunciation of words.. KWIM?
As for your DDad, Kelly, I imagine there are 1000s of peeps, who went through life with ailments such as mild MS and yet never DXed. In the old days, you were just having a bad spell..
