As for me I do not sleep with fans on, unless too uncomfortably hot/humid. After exposing my ears to all the non-sense daily noise I think it's best not to bombard them with more noise for another 8 hours.
I don't think hearing damage causes eustachian tube inflammation; that doesn't make physiological sense to me. Are you sure you're not allergic to something in your environment or in nature? That could cause all these symptoms.
