Re: spasm in ear in response to sounds
I get this too. I get it especially if I take vicodin, if I have a cold, if I'm very tired, or if I wear wool next to my skin (if I wear a long-sleeved undershirt, and the neckline of the sweater doesn't touch me, I am ok). It does happen randomly too, but I can count on it if I've got one of the four criteria above. I can not figure out how wool could possibly cause ear spasms. The others, I kind of understand, but wool?! I don't get rashes or anything from wool, just ear spasm noises and a kind of shivery feeling when it happens. It's really uncomfortable.
I am 30 and have been experience this at least since I was 14 or 15, maybe earlier. I remember I had a sweater in high school that made me feel physically ill every time I wore it (eventually I gave it away, but I'm betting it was wool). I've never asked a doctor about it because it's the least of my health concerns, but I can definitely relate!
