FWIW... Someone recently told me heavy use of aspirin can cause tinnitus. Could be as mine started around time I had to take lots of aspirin.
Yes, that is true. I, too, used a lot of aspirin at one time........................
A doctor once told me that the cause could be genetic. My Dad had it, but he attributed it to loud noises at the rail yard where he worked for almost 40 years. So who knows?
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.)
