I read that on the Internet so it must be true!
Seriously, I have read that at least a correlative relationship has been reported (in a few medical journals). A few ENT's I've visited also believe this. Myself, mine started after many years of using full strength aspirin almost daily for chronic headaches.
Curiously since starting the medication I'm taking now to help with the tinnitus, my chronic headaches have disappeared. So maybe there's some link there. (sadly my tinnitus hasn't but it's at least reduced somewhat.)
This was known before the transistor was invented, much less the Internet.................
