Olive oil would probably make a great lub, quite messy though
.
Oh man, I'm so sorry. I know an old lady who has it too and it's really hard for her.
If you ever try the olive oil thing, always use
extra-virgin olive oil, the best you can afford or find where you are (here it's part of our culture so it's virtually everywhere; in fact, my parents have a small orchard where they have some olive trees so all the virgin olive oil that is consumed in my family was produced by them.)
And of course, don't pour gallons of oil into the ear
. A little oil applied using a piece of gauze or a cotton ball will be enough.
