But the germs aren't smaller, I mean if a kid gets attacked by a bear...
The crystals thing is sweet as, BPPV, it's when crystals land on these balance-sensing hairs in your inner ear and give you vertigo, but there's this short maneuver exercise you do that dislodges them and shifts them somewhere else. I've had it a few times in my life and always shifted them no problem.
Some people get recurring BPPV and apparently you need a physio to help with some other manouver if they're in a hard to reach place.
But with a virus its when the actual part of your ear with the hairs in it gets inflamed and messes them up, can be for weeks, an unlucky few never recover properly. The manouvers don't touch it. Then the third cause is this thing called a vestibular migraine some people just get.
They both seem equally bad to me.
You don't have to have either problem though; both can be avoided easily.
