@Roseanna H I'm so glad you posted this because I've been wondering the same thing. In the 6 months I've had tinnitus, I've noticed I get earaches which come on after I've been exposed to more noise than usual. For instance, I went to a choral event last night that lasted 2 hours. It wasn't super loud, but it was a louder environment than usual and sustained. Plus there was a lot of applause between numbers, and I'd cringe whenever the clapping started. I came out of the show with a very sore left ear, and it's still sore today. It also feels "tight" if that makes any sense.
This soreness happened to me a few months ago when I attended a similar event, but that time I wore earplugs and thought the earplugs had caused the soreness. So this time I had the same soreness, but with no earplugs.
I came across this link which says its caused by contraction of the tensor tympani and that just the anticipation of a loud noise or THINKING about a loud noise can cause this contraction for some people, therefore my stress and worry over being at the concert could have caused the contraction and thus the pain. Or that's how I'm interpreting this. But my big question yesterday and today was how can noise cause physical pain? And it's not like a bomb went off next to me -- it was just a choral show.
