A very interesting treatment mentioned in traditional literature about tinnitus/deafness and the use of “gall of an ox” [mara] in the ear. [Sefer hanisyonot attributed to Abraham Ibn Ezra, page 179][edited, translated and commented by J.O. Leibowitz and S.Marcus,1984, Jersualem, The Magnes Press]

Many centuries later, a French herbalogist, Jean Palaiseulmentions the same idea in “grandmother’s secrets [“Penguin, 1976]

I am sure he did not read the Ibn Ezra and where would he have this tradition from?

If you feel like trying because nothing helped then go ahead.
