Went to an ear/nose/throat specialist (Dr. of the head-holes according to the Simpsons) and he said I was fine. Just happens after listening to IEMs. Ranges from "feel full" to "is this an ear infection pressure". Sinuses are good, but the easy solution was to follow the old joke:
Me: "doctor, my arm hurts when I wave it like this".
Doctor: "then don't wave it like that".
So IEMs are out for me...thus my journey this summer into portable headphones.
Hmmm, interesting. I guess if nothings wrong otherwise then youre good to go. I have had chronic ENT issues for years so I could never let it go like that. But thats me - at least you know its nothing serious.
