I don't have any answers, but wouldn't it be interesting to know? I think it is rooted in a real hypersensitivity. Sometimes lightbulbs make noises that drive me crazy. If other people listen, they can hear them too, but for some reason, it registers more strongly for me. I think there is a word for that, like when someone drumming their fingers drives you nuts even though it's not a loud noise.

Not sure where you are, but in cold areas this time of year, everyone is wearing hand lotion. Could that be what you smell on the papers? I hope it becomes less bothersome for you.
